Department of Mathematics Iiser Bhopal Phd Programme Manual (2021) DEPARTMENT OF MATHEMATICS IISER BHOPAL PHD PROGRAMME MANUAL (2021) DEPARTMENT-SPECIFIC GUIDELINES Refer to the PG Manual for Institute-wide guidelines for the Ph.D. programme. This document consists of guidelines specific to the Mathematics department. 1. COURSEWORK Students are required to take three mandatory courses in the first semester as described below. These courses cover the bare minimum background required for a student to begin preparatory study in the research areas represented in the department. First Semester Second Semester 1. MTH 601: Algebra I At least two DE 2. MTH 603: Real Analysis ● A student is allowed to credit at most one 3. MTH 605: Topology I reading course (4 credits) in the entire PhD 4. One Departmental curriculum Elective (DE) ● A student can also take Ph.D. thesis credits (4/8 credits) to meet 16 credit requirement in the semester Third semester onwards, a student can take DE/Reading course/Ph.D. thesis credits, as per the advice of DPGC Convener/supervisor. 2. GUIDELINES a. Assignment of Mentor Every PhD student will be assigned a mentor upon joining the program. The mentor will provide guidance to the student towards choosing the appropriate courses and also monitor the student’s progress from time-to-time until he/she finds a thesis supervisor. b. Assignment of Thesis Supervisor 1. Each student is required to choose a potential supervisor by the end of the first year. 2. Once chosen, the student must submit the duly filled change of supervisor form to the academic office, via Maths department office. c. Comprehensive Examination The comprehensive examination consists of two components, written and oral. As per the institute’s guidelines, the PhD students must clear the comprehensive examination(s) within a period of four registered semesters from the date of admission to the programme. ● Written Examination: The written exam will be of three-hour duration. This exam will be in one of the three core areas (algebra, analysis, geometry/topology). The syllabi of the same are detailed in a separate section later in the manual. The written exams will be conducted during the semester breaks (preferably, in December and July) after the completion of their first semester. The DPGC convener should nominate the chairperson of the question paper committee for each of the three subjects and each of the chairpersons should then form a committee of two to four faculty members from the department. Members of each such committee shall decide among themselves about the pass marks which they deem equivalent to a CPI of 7 on 10, and they should then grade the answer sheets. The student must submit Form A to the Department office by April 30 or October 30 to appear for the written comprehensive examination in July or December, respectively. This should be done in consultation with a potential thesis supervisor or DPGC (in case a potential supervisor has not been identified). As per institute’s guidelines, a student would get a maximum of two chances to clear the written comprehensive examination. ● Oral Examination: This exam cannot be taken unless the student has passed the written section and it is to be conducted by a committee consisting of the following members 1. Potential thesis supervisor. 2. At least one external expert, preferably, from within the institute. In case, the external member is from outside the institute, a suitable justification must be provided by the department. 3. Minimum two experts related to the topic. 4. One nominee of the HOD. 5. In case of repeated oral examinations, the HOD/ DPGC convener must attend the oral examination. This examination should consist of a presentation by the student followed by the interview by the committee. There will be no weightage of the written comprehensive exam in this round, and a student must independently clear the oral exam. Once again, as per institute’s guidelines, a student would get a maximum of two chances to clear the oral comprehensive examination. The student must submit Form B to the Department office at least 4 weeks prior to the oral exam along with the synopsis prepared in consultation with the potential thesis supervisor. The oral exam can be scheduled anytime subject to availability of the committee. d. Doctoral Advisory committee The thesis supervisor(s), in consultation with the DPGC, will form a Doctoral Advisory Committee (DAC), consisting of the supervisor(s) and at least two other faculty members from the department. The DAC will oversee the progress of the candidate towards completing the requirements for Ph.D. after the comprehensive exam has been successfully cleared. e. Annual Progress Seminar and Report Following successful completion of comprehensive exam requirements, each student is required to give an annual seminar based on the research progress made in the previous year and submit the report of progress towards the thesis. This report must be submitted to the DAC with a copy to Convener, DPGC. The timelines of these seminars and the submission of reports is announced by DPGC on a yearly basis. f. Graduate Seminars Each student has to clear two graduate seminars, as per the rules given in the Institute PG manual. In this regard, Form C must be submitted at least one month before the graduate seminar date. FORMS: Form A (Written Comprehensive Examination), Form B (Oral Comprehensive Examination with Synopsis), Form C (Graduate Seminar with DAC) are available at the department website. Other forms (such as the reports of various exams etc) are available on the Academic Office webpage. Reading Courses Students can register for a four-credit Reading Course (MTH 698) on a research topic with a prospective thesis supervisor prior to clearing the Ph.D. candidacy requirements. A student is allowed to credit at most one reading course in the entire PhD curriculum. ● This will be a semester long course with only one instructor. ● The goal of the course is two fold: - to promote a focused self-study, and - to provide the instructor and student the opportunity to work with each other. ● The student should register for the reading course during the pre-registration. The student should submit a hard copy of the title of the reading course with the instructor's signature, to the Department office, by the pre-registration deadline. ● The student should submit a hardcopy of the course contents for the reading course to the department office within a week after the classes begin. ● The evaluation in the course will be done by either the instructor or by a committee comprising three faculty members (including the instructor) based on the performance of the student in the material covered during the course, seminars/the end semester examination. ● In the case that the Reading course is evaluated solely by one instructor, the evaluation will also involve an end-semester examination. ● The instructor is expected to intimate the student about the evaluation policy in the beginning of the course. PhD Comprehensive Examination Syllabi ● Algebra ● Group Theory ● Groups: Groups, subgroups, cyclic groups, quotient groups, Lagrange’s theorem and some applications, isomorphism theorems. ● Group actions: Definition and examples, Cauchy’s theorem, class equation, Sylow’s theorems and its applications to finite groups. ● Other topics: Direct product, semi-direct product, derived series, upper and lower central series, basic results on solvable and nilpotent groups, structure theorem for finitely generated abelian groups, elementary divisors, invariant factors of a finite abelian group, free groups. ● Rings and Modules ● Rings: Rings, subrings, ideals, isomorphism theorems, principal, prime and maximal ideals, characterization of prime and maximal ideals, Chinese remainder theorem. ● Integral domains: Euclidean domain, Principal ideal domain, Unique factorization domain, primes and irreducible elements, Gauss’s lemma, Eisenstein’s criterion. ● Modules: Modules, submodules, quotient modules and isomorphism theorems, modules over PID, Jordan decomposition, rational canonical form, finitely generated modules, short exact sequence, short five lemma, tensor product and its properties. ● Fields and Galois theory ● Fields: Fields, subfields, characteristic of a field, finite and algebraic extensions, splitting fields, normal extensions, algebraic closure, separable extensions, cyclotomic fields, finite fields. ● Galois Theory: Primitive element theorem, fundamental theorem of Galois theory, computation of Galois groups.

  • 1.1.3 Reminder of Some Simple Topological Concepts Definition 1.1.17
    1. Preliminaries The Hausdorffcriterion could be paraphrased by saying that smaller neigh- borhoods make larger topologies. This is a very intuitive theorem, because the smaller the neighbourhoods are the easier it is for a set to contain neigh- bourhoods of all its points and so the more open sets there will be. Proof. Suppose τ τ . Fixed any point x X,letU (x). Then, since U ⇒ ⊆ ∈ ∈B is a neighbourhood of x in (X,τ), there exists O τ s.t. x O U.But ∈ ∈ ⊆ O τ implies by our assumption that O τ ,soU is also a neighbourhood ∈ ∈ of x in (X,τ ). Hence, by Definition 1.1.10 for (x), there exists V (x) B ∈B s.t. V U. ⊆ Conversely, let W τ. Then for each x W ,since (x) is a base of ⇐ ∈ ∈ B neighbourhoods w.r.t. τ,thereexistsU (x) such that x U W . Hence, ∈B ∈ ⊆ by assumption, there exists V (x)s.t.x V U W .ThenW τ . ∈B ∈ ⊆ ⊆ ∈ 1.1.3 Reminder of some simple topological concepts Definition 1.1.17. Given a topological space (X,τ) and a subset S of X,the subset or induced topology on S is defined by τ := S U U τ . That is, S { ∩ | ∈ } a subset of S is open in the subset topology if and only if it is the intersection of S with an open set in (X,τ). Alternatively, we can define the subspace topology for a subset S of X as the coarsest topology for which the inclusion map ι : S X is continuous.

  • Arxiv:2011.11669V2 [Math.LO] 18 Jul 2021 on Piecewise Hyperdefinable Groups
    On piecewise hyperdefinable groups Arturo Rodr´ıguez Fanlo July 20, 2021 Abstract The aim of this paper is to generalize and improve two of the main model-theoretic results of “Stable group theory and approximate sub- groups” [11] to the context of piecewise hyperdefinable sets. The first one is the existence of Lie models. The second one is the Stabilizer The- orem. In the process, a systematic study of the structure of piecewise hyperdefinable sets is developed. In particular, we show the most signifi- cant properties of their logic topologies. Acknowledgements I want to specially thank my supervisor, Prof. Ehud Hrushovski, for all his help, ideas and suggestions: without him it would not have been possible to do this. I also want to thank my PhD mate, Alex Chevalier, for his helpful reviews and comments. Introduction Various enlightening results were found in [11] with significant consequences on arXiv:2011.11669v2 [math.LO] 18 Jul 2021 model theory and additive combinatorics. Two of them are particularly relevant: the Stabilizer Theorem and the existence of Lie models. The Stabilizer Theorem [11, Theorem 3.5], already improved in [16, Theorem 2.12], was originally itself a generalization of the classical Stabilizer Theorem for stable and simple groups (see for example [21, Section 4.5]) changing the stability and simplicity hypotheses by some kind of measure-theoretic ones. Here, we extend that theorem to piecewise hyperdefinable groups in section 3. All this is easily done once we define properly dividing and forking for piecewise hyperdefinable sets. The proof we give is not new: it is essentially a combination of the original proof of [11] and the improved version of [16], adapted to the context of piecewise hyperdefinable groups.

  • Program in Pure Mathematics Is Intended
    55. MASTERS OF SCIENCE IN PURE MATHEMATICS 1. INTRODUCTION The Master of Science (M.Sc.) program in Pure Mathematics is intended to produce graduates whose areas of specialization are broad enough to carry out research, participate in national and international endeavors and disseminate knowledge through teaching. We propose establishing a new Postgraduate Master's program in mathematics called Pure Mathematics within the school of Mathematics and Actuarial Sciences at Bondo University College(BUC) . The Pure Mathematics program will offer an integrated interdisciplinary curriculum combining mathematics, and communication skills. The Pure mathematics two year Master's Program will be based upon a core curriculum and train students by having them participate in projects with practical deliverables. The program will place special emphasis on applications in science, engineering, and business. Projects are selected by an industrial mathematics course advisory board. The graduate will have studied not only the standard mathematical and statistical tools, but also the basic ideas of engineering and business, and will have received training in project development and in modes of industrial communication. 2. Rationale for the Program The importance of computer science in science, engineering, and business requires no justification. On the other hand, the role of mathematics is arguably as important, but not nearly as well understood or appreciated. Broadly speaking as the complexity, difficulty, size, or structure of a problem grows, mathematical analysis assumes increasing importance. An interdisciplinary program combining mathematics and information sciences is an research area that is critical to science and technology and in which BUC can build a research program of national significance.

  • ON Θ-CLOSED SETS and SOME FORMS of CONTINUITY 1. Introduction the Concepts of Δ-Closure, Θ-Closure, Δ-Interior and Θ-Interi
    ARCHIVUM MATHEMATICUM (BRNO) Tomus 40 (2004), 383 { 393 ON θ-CLOSED SETS AND SOME FORMS OF CONTINUITY MOHAMMAD SALEH Abstract. In this paper, we further the study of θ-compactness a general- ization of quasi-H-closed sets and its applications to some forms of continuity using θ-open and δ-open sets. Among other results, it is shown a weakly θ-retract of a Hausdorff space X is a δ-closed subset of X. 1. Introduction The concepts of δ-closure, θ-closure, δ-interior and θ-interior operators were first introduced by Veliˇcko. These operators have since been studied intensively by many authors. Although θ-interior and θ-closure operators are not idempotents, the collection of all δ-open sets in a topological space (X; Γ) forms a topology Γs on X, called the semiregularization topology of Γ, weaker than Γ and the class of all regular open sets in Γ forms an open basis for Γs. Similarly, the collection of all θ-open sets in a topological space (X; Γ) forms a topology Γθ on X, weaker than Γ. So far, numerous applications of such operators have been found in studying different types of continuous like maps, separation of axioms, and above all, to many important types of compactness [6], [7], [8], [10], [11], [12], [15], [16], [17]. A subset A of a space X is called a closure compact subset of X if every open cover of A has a finite subcollection whose closures cover A. A closure compact Hausdorff space is called H-closed, first defined by Alexandroff and Urysohn.

General topology is not so much a theory of topological spaces as it is a theory of continuous maps. For example, we will mostly study topological spaces by studying continuous maps into or out of them. For this reason, we can and will in Chapter I dwell on continuous maps between metric spaces for a while before actually defining topological spaces. Even more drastically, some topological spaces that we will meet shall be charac- terized by the continuous maps into or out of them. This point of view will be the main theme in Chapter II. In Chapter III we will see that two of the most prominent properties of topological spaces, the Hausdorff property and compactness, are actually better understood when they are thought of as specializations of properties of continuous maps.

E-mail: [email protected] August 26, 2017 Abstract We will introduce strongly inversely-I-open and strongly inversely-I-closed maps and give characterizations of these maps. We also give the relationship of these maps with pointwise-I-continuous maps. 2010 Mathematics Subject Classification. 54C08, 54C10 Keywords. Strongly inversely-I-open, strongly inversely-I-closed, pointwise-I-continuous, ideal. 1 Introduction and Preliminaries The subject of ideals in topological spaces has been studied by Kuratowski[2] and Vaidyanathaswamy[6]. An ideal I on a topological space (X; τ) is a collection of subsets of X which satisfies that (i) A 2 I and B 2 I implies A [ B 2 I and (ii) A 2 I and B ⊂ A implies B 2 I. Given a topological space (X; τ) with an ideal I on X known as ideal topological space and (:)∗ : }(X) ! }(X), called a local function[2] of A with respect to I and τ, is defined as follows: for A ⊆ X, A∗(I; τ) = fx 2 X : U \ A < I for every open nhd. U of x in Xg. A Kuratowski closure operator cl∗(:) for a topology τ∗(I; τ), called the ∗-topology, finer than τ, is defined by cl∗(A) = A [ A∗(I; τ)[5]. When there is no chance of confusion, we will simply write A∗ for A∗(I; τ) and τ∗(I) for τ∗(I; τ). Throughout this paper (X; τ) will denote topological space on which no separation axioms are assumed.

    EXISTENCE AND UNIQUENESS OF GLOBAL KOOPMAN EIGENFUNCTIONS FOR STABLE FIXED POINTS AND PERIODIC ORBITS MATTHEW D. KVALHEIM AND SHAI REVZEN Abstract. We consider C1 dynamical systems having an attracting hyperbolic fixed point or periodic orbit k k,α and prove existence and uniqueness results for C (actually Cloc ) linearizing semiconjugacies—of which Koopman eigenfunctions are a special case—defined on the entire basin of attraction. Our main results both generalize and sharpen Sternberg’s Ck linearization theorem for hyperbolic sinks, and in particular our corollaries include uniqueness statements for Sternberg linearizations and Floquet normal forms. Using our main results we also prove new existence and uniqueness statements for Ck Koopman eigenfunctions, including a complete classification of C∞ eigenfunctions assuming a C∞ dynamical system with semisimple and nonresonant linearization. We give an intrinsic definition of “principal Koopman eigenfunctions” which generalizes the definition of Mohr and Mezić for linear systems, and which includes the notions of “isostables” and “isostable coordinates” appearing in work by Ermentrout, Mauroy, Mezić, Moehlis, Wilson, and others. Our main results yield existence and uniqueness theorems for the principal eigenfunctions and isostable coordinates and also show, e.g., that the (a priori non-unique) “pullback algebra” defined in [MM16b] is unique under certain conditions. We also discuss the limit used to define the “faster” isostable coordinates in [WE18, MWMM19] in light of our main results. Contents 1. Introduction 1 1.1. Nontechnical overview of results2 1.2.

    EQUILIBRIUM STATES FOR NON-TRANSITIVE RANDOM OPEN AND CLOSED DYNAMICAL SYSTEMS JASON ATNIP, GARY FROYLAND, CECILIA GONZÁLEZ-TOKMAN, AND SANDRO VAIENTI Abstract. This work provides random Perron–Frobenius decompositions and relative equilibrium states for a class of random open and closed interval maps, without imposing transitivity requirements, such as mixing and covering conditions, which are prevalent in the literature. Such decompositions are linked to the existence and uniqueness of random conformal and invariant measures with exponential decay of correlations. These results allow us to expand the class of examples of (random) dynamical systems amenable to multiplicative ergodic theory and thermodynamic formalism. Applications include open and closed random intermittent maps with geometric potentials, non-transitive random maps and a connection between Lyapunov exponents and escape rates through random holes.
