Alexandre Jannaud (Sorbonne),Dehn-Seidel twist, $C^0$ symplectic geometry and barcodes
Abstract: In this talk I will present my work initiating the study of the $C^0$ symplectic mapping class group, i.e. the group of isotopy classes of symplectic...

Computer Science/Discrete Mathematics Seminar I

Graph Density Inequalities, Sums of Squares and Tropicalization
Annie Raymond
11:15am|Remote Access - see Zoom link below

Establishing inequalities among graph densities is a central pursuit in extremal graph theory. One way to certify the nonnegativity of a graph density expression is to write it as a sum of squares or as a rational sum of squares. In this talk, we...

Members’ Seminar

Estimating the mean of a real valued distribution
2:00pm|Simonyi Hall 101 and Remote Access

I revisit the basic statistical problem of estimating the mean of a real-valued distribution. I will introduce an estimator with the guarantee that "our estimator, on *any* distribution, is as accurate as the sample mean is for the Gaussian...

Analysis Seminar

Index theorems for nodal count and a lateral variation principle
Gregory Berkolaiko
4:30pm|Remote Access

Our study is motivated by earlier results about nodal count of Laplacian eigenfunctions on manifolds and graphs that share the same flavor: a normalized nodal count is equal to the Morse index of a certain energy functional at the critical point...
