DESCRIPTION:Featured Speaker: Tasuki Kinjo (University of Tokyo)\n\nTitle:
Cohomological Donaldson-Thomas theory for 2-Calabi--Yau categories.\n\nAbst
ract: Cohomological Donaldson-Thomas (CoDT) invariants were introduced by
Kontsevich-Soibelman and Brav-Bussi-Dupont-Joyce-Szendroi as categorificati
ons of the Donaldson-Thomas invariants counting objects in 3-Calabi-Yau cat
egories. In this talk\, I will explain applications of the CoDT theory to t
he cohomological study of the moduli of objects in 2-Calabi-Yau categories.
Among other things\, I will construct a coproduct on the Borel-Moore homol
ogy of the moduli stack of objects in these categories and establish a PBW-
type statement for the Kapranov-Vasserot cohomological Hall algebras. This
talk is based on a joint work in progress with Ben Davison.
