SUMMARY:The Sceptical Mathematician: How John Wallis Saved Mathematics for the Royal Society (Amir Alexander\, UCLA)
DESCRIPTION:The members of the “Invisible College” and the early Royal Society championed an experimental approach to the study of nature as the proper path to the advancement of knowledge and the preservation of civic peace. Mathematics\, while admired\, was also viewed with suspicion\, as potentially dogmatic and coercive. John Wallis\, the leading mathematician in the group\, set out to reconcile his field with the ideals of the early Royal Society by developing a radical new approach. Whereas traditional mathematics prided itself on irrefutable deductive proofs\, Wallis’ approach relied on material intuition\, inductive reasoning\, and truth-claims founded on consensus\, not coercion. It was a new mathematics modeled on the Society’s experimental philosophy.

SUMMARY:Applied Math Seminar: Angel Chavez (Pomona)
DESCRIPTION:Title: Randomized Sums of Graph Spectra \nAbstract:\nThe adjacency matrix of an Erdős-Rényi-Gilbert graph is a random symmetric matrix whose entries are Bernoulli random variables. These entries\, modulo the constraints imposed by symmetry\, are independent. We aim to understand the asymptotic behavior of randomized sums of the spectra and singular spectra of these matrices. In particular\, we establish several central-limit type theorems for these randomized sums of eigenvalues and singular values.

SUMMARY:Factoring translates of polynomials (Arvind Suresh\, University of Arizona - Tucson)
DESCRIPTION:Given a degree d polynomial f(x) in Q[x]\, consider the subset S_f  of Q consisting of rational numbers t for which the translated polynomial f(x) – t factors completely in Q[x]. For example\, if f is linear or quadratic then S_f is always infinite\, but if degree of f is at least 3\, then interesting things can happen. In this talk\, we discuss a connection between the set S_f and the classical Prouhet–Tarry–Escott problem (which asks for integer solutions to certain symmetric family of equations)\, and we present two infinite families of polynomials f for which S_f is infinite (upon replacing Q with certain number fields). Time permitting\, we outline how these can then be used to produce algebraic curves over number fields having a record number of rational points (relative to their genus).

SUMMARY:Prof. Edouard Oudet
DESCRIPTION:Title: Shape Optimization: Old and New \nSpeaker: Edouard Oudet\,  LJK\, Université Grenoble Alpes \nAbstract: We first introduce what is shape Optimization and the most classical problems of the field like the isoperimetric problem\, the study of minimal surfaces\, the characterization of irrigation networks\, etc. In a second step we focus on a more recent question related to Lebesgue-Santalo diagrams.  We show how tools from discrete geometry contributed to approximate in a very precise and efficient way these diagrams. \n\n\n\n\n\nEdouard Oudet is Professor of Applied Mathematics at University Grenoble Alpes and a member of Laboratoire Jean Kuntzmann  since 2010. His research interests include calculus of variation\, shape optimization\, optimal transportation and spectral theory. He has supervised or co-supervised 8 PhD theses and has written 50 articles in peer-reviewed international journals (ARMA\, Numerische Mathematik\, SIMA\, SICON\, JMIV\, . . . ). Since October 2022 he is a senior member of the IUF “Institut Universitaire de France”.

SUMMARY:Norms on self-adjoint symmetric tensor power of linear operators on Hilbert spaces (Yunied Puig de Dios\, CMC)
DESCRIPTION:We introduce a family of norms on the space of self-adjoint trace class symmetric tensor power of linear operators acting on an infinite-dimensional Hilbert space. Our technique is to extend to infinite dimension an original and nice idea of a very recent result by K. Aguilar\,  Á. Chávez\, S. R. Garcia and J. Volčič\, in which the authors introduce a family of norms on the space of n x n  complex matrices induced by complete homogeneous symmetric polynomials. This is a work in progress paper\, so it goes without saying that it will be very much appreciated any comment or/and suggestion coming from the audience. This is joint work with K. Aguilar\, Á. Chávez and S. R. Garcia.
