Number Theory Seminar: October 21, 2024
Oct. 21, 2024—Location: 12 p.m. in Buttrick Hall, room 206 Speaker: Hui Xue (Clemson University) Title: Subspaces spanned by eigenforms with nonzero central L-values Abstract: In this talk, we discuss explicit spanning sets for two vector spaces. One is the subspace generated by integral-weight Hecke eigenforms with nonzero central L- values. The other is a subspace generated by...
Number Theory Seminar: October 18, 2024
Oct. 18, 2024—Location: 12:10 p.m. in Stevenson Center, room 1310 Speaker: Walter Bridges (University of North Texas) Title: Zero attractors and sign changes in partition polynomials Abstract: I will discuss new methods in the asymptotic theory of integer partitions with applications to the following two problems. The first problem concerns secondary terms in asymptotic equidistribution. For example, if $p(a,b,n)$ denotes...
Colloquium – Talk by Darren Creutz and Mike Neamtu: October 17, 2024
Oct. 17, 2024—October 17, 2024 (Thursday), 4:10 p.m. Darren Creutz, Vanderbilt University Mike Neamtu, Vanderbilt University Darren Creutz, Symbolic Dynamics: Connecting short-term and long-term complexity in dynamical systems Given a dynamical system and a (reasonable) partition of the space, there isa natural map from the system to a symbolic system: assign each element of the partition a...
John Jumper BS Math ’07 wins Nobel Prize
Oct. 9, 2024—John Jumper, who received a BS degree in Mathematics and Physics from Vanderbilt in 2007, has won a share of the 2024 Nobel Prize in Chemistry. Jumper works as American Director at Google DeepMind Technologies. His team created the AI model AlphaFold, which predicts protein structures from their amino acid sequence. About his work Jumper...
Geometry and Topology Seminar: October 4, 2024
Oct. 7, 2024—Speaker: Sofia Martinez Alberga (Purdue University) Title: Modeling Equivariant Simplicial Sets with Simplicial Coalgebras Abstract: Given a commutative ring R, a $\pi_1$-R-equivalence is a continuous map of spaces inducing an isomorphism on fundamental groups and an R-homology equivalence between universal covers. When R is an algebraically closed field, Raptis and Rivera described a full and faithful model for the homotopy...
Colloquium – Talk by Mark Ellingham and Rares Rasdeaconu: October 3, 2024
Oct. 3, 2024—October 3, 2024 (Thursday), 4:10 pm Mark Ellingham and Rares Rasdeaconu, Vanderbilt University “Maximum genus directed embeddings of digraphs” Mark Ellingham, Vanderbilt University In topological graph theory we often want to find embeddings of a given connected graph with minimum genus, so that the underlying compact orientable surface of the embedding is as simple as...
Geometry and Topology Seminar: Friday, September 27th
Sep. 27, 2024—Speaker: Garrett Michael Brown (UC Berkeley) Title: The sign of scalar curvature on Kaehler blowups Abstract: In Kaehler geometry there is a compelling interaction between the curvature of the metric and the underlying algebro-geometric structure. One example is that positivity of the scalar curvature forces the the Kodaira dimension to be negative. I will explain a recent resolution to the...

A baker’s dozen yogis were led by Highland Yoga instructor Kelly Swanton in an invigorating session of vinyasa-style yoga. Free yoga mats were distributed to all undergraduates who needed one. Department Chair Dan Margalit participated. In his words,...
Colloquium – Amenability, optimal transport and abstract ergodic theorems : September 19, 2024
Sep. 19, 2024—September 19, 2024 (Thursday), 4:10 pm Christian Rosendal, University of Maryland The concept of amenability is ubiquitous in functional analysis, group theory and logic. In general, amenability of, for example, a group allows one to integrate bounded real valued functions on the group in a translation invariant manner, which is of great utility in many...
