Implications for Understanding the Role of Affect in Mathematical Thinking
Mathematicians and music: Implications for understanding the role of affect in mathematical thinking Rena E. Gelb Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2021 © 2021 Rena E. Gelb All Rights Reserved Abstract Mathematicians and music: Implications for understanding the role of affect in mathematical thinking Rena E. Gelb The study examines the role of music in the lives and work of 20th century mathematicians within the framework of understanding the contribution of affect to mathematical thinking. The current study focuses on understanding affect and mathematical identity in the contexts of the personal, familial, communal and artistic domains, with a particular focus on musical communities. The study draws on published and archival documents and uses a multiple case study approach in analyzing six mathematicians. The study applies the constant comparative method to identify common themes across cases. The study finds that the ways the subjects are involved in music is personal, familial, communal and social, connecting them to communities of other mathematicians. The results further show that the subjects connect their involvement in music with their mathematical practices through 1) characterizing the mathematician as an artist and mathematics as an art, in particular the art of music; 2) prioritizing aesthetic criteria in their practices of mathematics; and 3) comparing themselves and other mathematicians to musicians. The results show that there is a close connection between subjects’ mathematical and musical identities. I identify eight affective elements that mathematicians display in their work in mathematics, and propose an organization of these affective elements around a view of mathematics as an art, with a particular focus on the art of music. -
Langlands Program, Trace Formulas, and Their Geometrization
BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY Volume 50, Number 1, January 2013, Pages 1–55 S 0273-0979(2012)01387-3 Article electronically published on October 12, 2012 LANGLANDS PROGRAM, TRACE FORMULAS, AND THEIR GEOMETRIZATION EDWARD FRENKEL Notes for the AMS Colloquium Lectures at the Joint Mathematics Meetings in Boston, January 4–6, 2012 Abstract. The Langlands Program relates Galois representations and auto- morphic representations of reductive algebraic groups. The trace formula is a powerful tool in the study of this connection and the Langlands Functorial- ity Conjecture. After giving an introduction to the Langlands Program and its geometric version, which applies to curves over finite fields and over the complex field, I give a survey of my recent joint work with Robert Langlands and NgˆoBaoChˆau on a new approach to proving the Functoriality Conjecture using the trace formulas, and on the geometrization of the trace formulas. In particular, I discuss the connection of the latter to the categorification of the Langlands correspondence. Contents 1. Introduction 2 2. The classical Langlands Program 6 2.1.

Fundamental Theorems in Mathematics
SOME FUNDAMENTAL THEOREMS IN MATHEMATICS OLIVER KNILL Abstract. An expository hitchhikers guide to some theorems in mathematics. Criteria for the current list of 243 theorems are whether the result can be formulated elegantly, whether it is beautiful or useful and whether it could serve as a guide [6] without leading to panic. The order is not a ranking but ordered along a time-line when things were writ- ten down. Since [556] stated “a mathematical theorem only becomes beautiful if presented as a crown jewel within a context" we try sometimes to give some context. Of course, any such list of theorems is a matter of personal preferences, taste and limitations. The num- ber of theorems is arbitrary, the initial obvious goal was 42 but that number got eventually surpassed as it is hard to stop, once started. As a compensation, there are 42 “tweetable" theorems with included proofs. More comments on the choice of the theorems is included in an epilogue. For literature on general mathematics, see [193, 189, 29, 235, 254, 619, 412, 138], for history [217, 625, 376, 73, 46, 208, 379, 365, 690, 113, 618, 79, 259, 341], for popular, beautiful or elegant things [12, 529, 201, 182, 17, 672, 673, 44, 204, 190, 245, 446, 616, 303, 201, 2, 127, 146, 128, 502, 261, 172].

After a few long seconds of silence the movie theater went dark.

I’d seen it countless times in the editing studio, on my computer, on TV... But watching it for the first time on a panoramic screen was a special moment which brought up memories from the year before. I was in Paris as the recipient of the firstChaire d’Excellence awarded by Fonda- tion Sciences Mathématiques de Paris, invited to spend a year in Paris doing research and lecturing about it. ___ 1 Parts of this article are borrowed from my book Love and Math. 2 For more information about the film, visit http://ritesofloveandmath.com, and about the book, http://edwardfrenkel.com/lovemath. ©2015 Edward Frenkel 70 EDWARD FRENKEL Paris is one of the world’s centers of mathematics, but also a capital of cinema. Being there, I felt inspired to make a movie about math. In popular films, math- ematicians are usually portrayed as weirdos and social misfits on the verge of mental illness, reinforcing the stereotype of mathematics as a boring and irrel- evant subject, far removed from reality. Would young people want a career in math or science after watching these movies? I thought something had to be done to confront this stereotype. -

Creative Discomfort: the Culture of the Gelfand Seminar at Moscow University Slava Gerovitch
Creative Discomfort: The Culture of the Gelfand Seminar at Moscow University Slava Gerovitch 1 Memory Israel Gelfand’s weekly seminar at Moscow State University, which ran continu- ously from 1943 to 1989, has gained a legendary status in the Russian mathematics community. It has been praised as “maybe the greatest seminar in the history of the Mechanical-Mathematical Faculty of Moscow University,”1 “probably the best seminar in the history of mathematics,”2 and even “one of the most productive seminars in the history of science.”3 According to seminar participants, the seminar “ardently followed all that was new in mathematics anywhere in the world”4 and “made a decisive impact on mathematical life in Moscow.”5 Many outstanding mathematicians remember the seminar fondly as their crucial coming-of-age experience. Before we conjure up an idyllic image of a harmonic chorus of great mathe- maticians conversing magnificently on topics of utmost scholarly importance, let us read a bit more from the memoirs of the same seminar participants. The seminar has 1Tikhomirov (2008), p. 10. 2Interview with Aleksei Sosinskii, 20 October 2009 (http://polit.ru/article/2009/10/20/absossinsky_ about_imgelfand/). 3Tikhomirov (2008), p. 25. 4Landis (2007), p. 69. 5Arnold (2009), p. 40.

A Mathematician's View of the Unreasonable Ineffectiveness Of
A MATHEMATICIAN'S VIEW OF THE UNREASONABLE INEFFECTIVENESS OF MATHEMATICS IN BIOLOGY. ALEXANDRE BOROVIK Abstract. This paper discusses, from a mathematician's point of view, the thesis formulated by Israel Gelfand, one of the greatest mathematicians of the 20th century, and one of the pioneers of mathematical biology: There is only one thing which is more unreasonable than the unreasonable effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology. Disclaimer. The author writes in his personal capacity and views expressed do not represent position of any other person, corporation, organisation, or institution. 1. Israel Gelfand and his views on the role of mathematics in biology Perhaps a disclaimer is necessary: I am a mathematician, not a biologist. I was invited to write this paper because I found myself in a strange role of a custodian of a particular saying by Israel Gelfand, one of the greatest mathematicians of the 20th century, and a pioneer of mathematical biology. My blog [16] became its principal source: Eugene Wigner wrote a famous essay [55] on the unreasonable effective- ness of mathematics in natural sciences. He meant physics, of course. There is only one thing which is more unreasonable than the unreason- able effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology. I wish to confirm that, indeed, I heard these words from Israel Gelfand in private conversations (and more than once) in about 1995{2005. Beyond that, everything in this paper is my opinion or my reconstruction of Gelfand's view of science and life from my conversations with him; I understand of course that my assessments arXiv:2103.04190v1 [math.HO] 6 Mar 2021 could be very lopsided. -
