Geometric and Modular Representation Theory Seminar

The Hecke category action on the principal block via Smith theory
3:00pm|Simonyi Hall 101 and Remote Access

Wall-crossing functors on the principal block of category $O$ give an action of the (finite) Hecke category. If one knows enough about the Hecke category, one can deduce the Kazhdan-Lusztig conjectures from the existence of this action. This is a...

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...
