Woyczyński Case Western Reserve University Universitext is a series of textbooks that presents material from a wide variety of mathematical disciplines at master’s level and beyond. The books, often well class-tested by their author, may have an informal, personal even experimental approach to their subject matter. Some of the most successful and established books in the series have evolved through several editions, always following the evolution of teaching curricula, into very polished texts. Thus as research topics trickle down into graduate-level teaching, first textbooks written for new, cutting-edge courses may make their way into Universitext.

After Ramanujan Left Us– a Stock-Taking Exercise S
Ref: after-ramanujanls.tex Ver. Ref.: : 20200426a After Ramanujan left us– a stock-taking exercise S. Parthasarathy [email protected] 1 Remembering a giant This article is a sequel to my article on Ramanujan [14]. April 2020 will mark the death centenary of the legendary Indian mathe- matician – Srinivasa Ramanujan (22 December 1887 – 26 April 1920). There will be celebrations of course, but one way to honour Ramanujan would be to do some introspection and stock-taking. This is a short survey of notable achievements and contributions to mathematics by Indian institutions and by Indian mathematicians (born in India) and in the last hundred years since Ramanujan left us. It would be highly unfair to compare the achievements of an individual, Ramanujan, during his short life span (32 years), with the achievements of an entire nation over a century. We should also consider the context in which Ramanujan lived, and the most unfavourable and discouraging situation in which he grew up. We will still attempt a stock-taking, to record how far we have moved after Ramanujan left us. Note : The table below should not be used to compare the relative impor- tance or significance of the contributions listed there. It is impossible to list out the entire galaxy of mathematicians for a whole century. The table below may seem incomplete and may contain some inad- vertant errors.

These states represent the two generators of the Heegaard Floer homology of the knot in its topmost filtration level. The fact that these elements are homologically non-trivial can be used to show that the Seifert genus of this knot is two, a result first proved by David Gabai.

He is almost unique in his ability to fuse hyperbolic ‘tilings’. These ‘tiles’ carry a great deal of information that are significant in algebraic and analytic ideas to solve concrete and hard number theory. For example they are very problems in number theory. In addition, Venkatesh’s work on the interested in the characteristic frequencies of cohomology of arithmetic groups the tiles. These are the frequencies the tiles studies the shape of these tiles and would vibrate at, if they were used as drums. “I think there’s a lot of math in the world that’s not connects it with other areas of math. at university. Pure math is only one part of math but math is used in a lot of other subjects and I think that’s just as interesting.

In his undergraduate thesis he gave an elegant new construction of Seiberg-Witten Floer homology, and in his Ph.D. thesis he gave a remarkable gluing formula for the Bauer-Furuta invariants of four-manifolds. His research interests span the areas of gauge theory, low-dimensional topology, symplectic geometry and algebraic topology. Manolescu will begin his four-year appointment as a Research Fellow at Princeton University beginning July 1, 2004. Maryam Mirzakhani Maryam Mirzakhani (b. 1977), a native of Iran, is completing her Ph.D. at Harvard under the direction of Curtis T. McMullen. In her thesis she showed how to compute the Weil- Petersson volume of the moduli space of bordered Riemann surfaces. Her research interests include Teichmuller theory, hyperbolic geometry, ergodic theory and symplectic geometry. As a high school student, Mirzakhani entered and won the International Mathematical Olympiad on two occasions (in 1994 and 1995). Mirzakhani will conduct her research at Princeton University at the start of her four-year appointment as a Research Fellow beginning July 1, 2004. -
Man and Machine Thinking About the Smooth 4-Dimensional Poincaré
Quantum Topology 1 (2010), xxx{xxx Quantum Topology c European Mathematical Society Man and machine thinking about the smooth 4-dimensional Poincar´econjecture. Michael Freedman, Robert Gompf, Scott Morrison and Kevin Walker Mathematics Subject Classification (2000).57R60 ; 57N13; 57M25 Keywords.Property R, Cappell-Shaneson spheres, Khovanov homology, s-invariant, Poincar´e conjecture Abstract. While topologists have had possession of possible counterexamples to the smooth 4-dimensional Poincar´econjecture (SPC4) for over 30 years, until recently no invariant has existed which could potentially distinguish these examples from the standard 4-sphere. Rasmussen's s- invariant, a slice obstruction within the general framework of Khovanov homology, changes this state of affairs. We studied a class of knots K for which nonzero s(K) would yield a counterexample to SPC4. Computations are extremely costly and we had only completed two tests for those K, with the computations showing that s was 0, when a landmark posting of Akbulut [3] altered the terrain. His posting, appearing only six days after our initial posting, proved that the family of \Cappell{Shaneson" homotopy spheres that we had geared up to study were in fact all standard. The method we describe remains viable but will have to be applied to other examples. Akbulut's work makes SPC4 seem more plausible, and in another section of this paper we explain that SPC4 is equivalent to an appropriate generalization of Property R (\in S3, only an unknot can yield S1 × S2 under surgery"). We hope that this observation, and the rich relations between Property R and ideas such as taut foliations, contact geometry, and Heegaard Floer homology, will encourage 3-manifold topologists to look at SPC4. -

Mom Technology and Volumes of Hyperbolic 3-Manifolds 3
1 MOM TECHNOLOGY AND VOLUMES OF HYPERBOLIC 3-MANIFOLDS DAVID GABAI, ROBERT MEYERHOFF, AND PETER MILLEY 0. Introduction This paper is the first in a series whose goal is to understand the structure of low-volume complete orientable hyperbolic 3-manifolds. Here we introduce Mom technology and enumerate the hyperbolic Mom-n manifolds for n ≤ 4. Our long- term goal is to show that all low-volume closed and cusped hyperbolic 3-manifolds are obtained by filling a hyperbolic Mom-n manifold, n ≤ 4 and to enumerate the low-volume manifolds obtained by filling such a Mom-n. William Thurston has long promoted the idea that volume is a good measure of the complexity of a hyperbolic 3-manifold (see, for example, [Th1] page 6.48). Among known low-volume manifolds, Jeff Weeks ([We]) and independently Sergei Matveev and Anatoly Fomenko ([MF]) have observed that there is a close con- nection between the volume of closed hyperbolic 3-manifolds and combinatorial complexity. One goal of this project is to explain this phenomenon, which is sum- marized by the following: Hyperbolic Complexity Conjecture 0.1. (Thurston, Weeks, Matveev-Fomenko) The complete low-volume hyperbolic 3-manifolds can be obtained by filling cusped hyperbolic 3-manifolds of small topological complexity. Remark 0.2. Part of the challenge of this conjecture is to clarify the undefined adjectives low and small. In the late 1970’s, Troels Jorgensen proved that for any positive constant C there is a finite collection of cusped hyperbolic 3-manifolds from which all complete hyperbolic 3-manifolds of volume less than or equal to C can be obtained by Dehn filling.
