Self-duality in quantum K-theory

October 20, 2020      8:00 pm
Speaker: Henry Liu

When we upgrade from equivariant cohomology to equivariant K-theory, many important algebraic/geometric tools such as dimensional vanishing become inapplicable in general. I will explain some nice conditions we can impose on K-theory...

Stringy invariants and toric Artin stacks

October 20, 2020      3:00 pm
Speaker: Jeremy Usatine

Stringy Hodge numbers are certain generalizations, to the singular setting, of Hodge numbers. Unlike usual Hodge numbers, stringy Hodge numbers are not defined as dimensions of cohomology groups. Nonetheless, an...

Exploring small fusion rings and tensor categories

October 20, 2020      10:00 am
Speaker: Joost Slingerland

I discuss some strategies for finding fusion rings of low rank (or if you prefer, fusion rules for a small number of objects) and corresponding tensor categories, or solutions to...
