Title: The integrality conjecture and the Kac positivity conjecture
Speaker: Ben Davison
Speaker Info: University of Glasgow and IST Austria
Brief Description:
Abstract:

Without assuming knowledge of any incarnation of Donaldson-Thomas theory, I'll give an introduction to the categorified version of it. I'll also explain what this upgrade of DT theory has to do with proving positivity conjectures, via my favourite example: the Kac positivity conjecture (originally proved by Hausel Letellier and Villegas), stating that polynomials counting absolutely indecomposable representations of quivers over Fq have positive coefficients.
