  • Questions About Boij-S\" Oderberg Theory
    QUESTIONS ABOUT BOIJ–SODERBERG¨ THEORY DANIEL ERMAN AND STEVEN V SAM 1. Background on Boij–Soderberg¨ Theory Boij–S¨oderberg theory focuses on the properties and duality relationship between two types of numerical invariants. One side involves the Betti table of a graded free resolution over the polynomial ring. The other side involves the cohomology table of a coherent sheaf on projective space. The theory began with a conjectural description of the cone of Betti tables of finite length modules, given in [10]. Those conjectures were proven in [25], which also described the cone of cohomology tables of vector bundles and illustrated a sort of duality between Betti tables and cohomology tables. The theory itself has since expanded in many directions: allowing modules whose support has higher dimension, replacing vector bundles by coherent sheaves, working over rings other than the polynomial ring, and so on. But at its core, Boij–S¨oderberg theory involves: (1) A classification, up to scalar multiple, of the possible Betti tables of some class of objects (for example, free resolutions of finitely generated modules of dimension ≤ c). (2) A classification, up to scalar multiple, of the cohomology tables of some class of objects (for examples, coherent sheaves of dimension ≤ n − c). (3) Intersection theory-style duality results between Betti tables and cohomology tables. One motivation behind Boij and S¨oderberg’s conjectures was the observation that it would yield an immediate proof of the Cohen–Macaulay version of the Multiplicity Conjectures of Herzog–Huneke–Srinivasan [44]. Eisenbud and Schreyer’s [25] thus yielded an immediate proof of that conjecture, and the subsequent papers [11, 26] provided a proof of the Mul- tiplicity Conjecture for non-Cohen–Macaulay modules.

  • The Probl\Eme Des M\'Enages Revisited
    The probl`emedes m´enages revisited Lefteris Kirousis and Georgios Kontogeorgiou Department of Mathematics National and Kapodistrian University of Athens [email protected], [email protected] August 13, 2018 Abstract We present an alternative proof to the Touchard-Kaplansky formula for the probl`emedes m´enages, which, we believe, is simpler than the extant ones and is in the spirit of the elegant original proof by Kaplansky (1943). About the latter proof, Bogart and Doyle (1986) argued that despite its cleverness, suffered from opting to give precedence to one of the genders for the couples involved (Bogart and Doyle supplied an elegant proof that avoided such gender-dependent bias). The probl`emedes m´enages (the couples problem) asks to count the number of ways that n man-woman couples can sit around a circular table so that no one sits next to her partner or someone of the same gender. The problem was first stated in an equivalent but different form by Tait [11, p. 159] in the framework of knot theory: \How many arrangements are there of n letters, when A cannot be in the first or second place, B not in the second or third, &c." It is easy to see that the m´enageproblem is equivalent to Tait's arrangement problem: first sit around the table, in 2n! ways, the men or alternatively the women, leaving an empty space between any two consecutive of them, then count the number of ways to sit the members of the other gender. Recurrence relations that compute the answer to Tait's question were soon given by Cayley and Muir [2,9,3, 10].

His unexpected death came as a tremendous shock to all who knew him. There had not been any danger signals. It was hard to realize that a person of such strong vitality was gone, that such a great mind had been extinguished by a physical failure of the body. Artin was born in Vienna on March 3,1898. He grew up in Reichen- berg, now Tschechoslovakia, then still part of the Austrian empire. His childhood seems to have been lonely. Among the happiest periods was a school year which he spent in France. What he liked best to remember was his enveloping interest in chemistry during his high school days. In his own view, his inclination towards mathematics did not show before his sixteenth year, while earlier no trace of mathe­ matical aptitude had been apparent.1 I have often wondered what kind of experience it must have been for a high school teacher to have a student such as Artin in his class. During the first world war, he was drafted into the Austrian Army. After the war, he studied at the University of Leipzig from which he received his Ph.D. in 1921. He became "Privatdozent" at the Univer­ sity of Hamburg in 1923.

  • Right Ideals of a Ring and Sublanguages of Science
    RIGHT IDEALS OF A RING AND SUBLANGUAGES OF SCIENCE Javier Arias Navarro Ph.D. In General Linguistics and Spanish Language http://www.javierarias.info/ Abstract Among Zellig Harris’s numerous contributions to linguistics his theory of the sublanguages of science probably ranks among the most underrated. However, not only has this theory led to some exhaustive and meaningful applications in the study of the grammar of immunology language and its changes over time, but it also illustrates the nature of mathematical relations between chunks or subsets of a grammar and the language as a whole. This becomes most clear when dealing with the connection between metalanguage and language, as well as when reflecting on operators. This paper tries to justify the claim that the sublanguages of science stand in a particular algebraic relation to the rest of the language they are embedded in, namely, that of right ideals in a ring. Keywords: Zellig Sabbetai Harris, Information Structure of Language, Sublanguages of Science, Ideal Numbers, Ernst Kummer, Ideals, Richard Dedekind, Ring Theory, Right Ideals, Emmy Noether, Order Theory, Marshall Harvey Stone. §1. Preliminary Word In recent work (Arias 2015)1 a line of research has been outlined in which the basic tenets underpinning the algebraic treatment of language are explored. The claim was there made that the concept of ideal in a ring could account for the structure of so- called sublanguages of science in a very precise way. The present text is based on that work, by exploring in some detail the consequences of such statement. §2. Introduction Zellig Harris (1909-1992) contributions to the field of linguistics were manifold and in many respects of utmost significance.

  • A Century of Mathematics in America, Peter Duren Et Ai., (Eds.), Vol
    Garrett Birkhoff has had a lifelong connection with Harvard mathematics. He was an infant when his father, the famous mathematician G. D. Birkhoff, joined the Harvard faculty. He has had a long academic career at Harvard: A.B. in 1932, Society of Fellows in 1933-1936, and a faculty appointmentfrom 1936 until his retirement in 1981. His research has ranged widely through alge­ bra, lattice theory, hydrodynamics, differential equations, scientific computing, and history of mathematics. Among his many publications are books on lattice theory and hydrodynamics, and the pioneering textbook A Survey of Modern Algebra, written jointly with S. Mac Lane. He has served as president ofSIAM and is a member of the National Academy of Sciences. Mathematics at Harvard, 1836-1944 GARRETT BIRKHOFF O. OUTLINE As my contribution to the history of mathematics in America, I decided to write a connected account of mathematical activity at Harvard from 1836 (Harvard's bicentennial) to the present day. During that time, many mathe­ maticians at Harvard have tried to respond constructively to the challenges and opportunities confronting them in a rapidly changing world. This essay reviews what might be called the indigenous period, lasting through World War II, during which most members of the Harvard mathe­ matical faculty had also studied there. Indeed, as will be explained in §§ 1-3 below, mathematical activity at Harvard was dominated by Benjamin Peirce and his students in the first half of this period. Then, from 1890 until around 1920, while our country was becoming a great power economically, basic mathematical research of high quality, mostly in traditional areas of analysis and theoretical celestial mechanics, was carried on by several faculty members.

    VOL. 35, 1949 MA THEMA TICS: I. KAPLANSK Y 133 PRIMARY IDEALS IN GROUP ALGEBRAS* BY IRVING KAPLANSKY INSTITUTE FOR ADVANCED STUDY Communicated by M. H. Stone, January 29, 1949 Let G be a locally compact abelian group and A its Li-algebra, that is, the algebra of all complex functions summable with respect to Haar measure, with convolution as multiplication. Let I be a closed ideal in A. A question stemming from Wiener's Tauberian investigations is the following: is I the intersection of the regular maximal ideals containing it? L. Schwartz1 has recently published a counter-example. This nega- tive result increases the interest in special cases where the answer is affirma- tive. Ditkin,2 Beurling3 and Segal4 have obtained an affirmative answer in the following case: I is a primary ideal (that is, it is contained in exactly one regular maximal ideal), and G is the group of real numbers or the group of integers. The purpose of this note is to extend this result to any locally compact abelian group. This will be accomplished by the methods of Segal, together with the structure theorems for groups. The essential idea is that the discrete case can be treated "elementwise," and thus reduced to the case of a cyclic group. THEOREM 1. In the Li-algebra of a localiy compact- abelian group, any closed primary ideal is maximal. In the proof we shall use the following lemma, which is a slight extension of Lemma 2.7.1 in S. LEMMA 1. Let R be the direct sum of a finite number of groups, each of which is the group of real numbers or of integers.

    OBITUARY NATHAN JACOBSON (1910–1999) Nathan Jacobson, who died on 5 December 1999, was an outstanding algebraist, whose work on almost all aspects of algebra was of fundamental importance, and whose writings will exercise a lasting influence. He had been an honorary member of the Society since 1972. Nathan Jacobson (later known as ‘Jake’ to his friends) was born in Warsaw (in what he describes as the ‘Jewish ghetto’) on 5 October 1910 (through an error some documents have the date 8 September); he was the second son of Charles Jacobson (as he would be known later) and his wife Pauline, nee´ Rosenberg. His family emigrated to the USA during the First World War, first to Nashville, Tennessee, where his father owned a small grocery store, but they then settled in Birmingham, Alabama, where Nathan received most of his schooling. Later the family moved to Columbus, Mississippi, but the young Nathan entered the University of Alabama in 1926 and graduated in 1930. His initial aim was to follow an uncle and obtain a degree in law, but at the same time he took all the (not very numerous) mathematics courses, in which he did so well that he was offered a teaching assistantship in Bull.
