Algebraic Geometry Seminar - Yunfeng Jiang
Title: On the motivic Joyce-Song formula of Behrend function identitiesSpeaker: Yunfeng Jiang (University of Kansas)Abstract: Then Behrend function, introduced by K. Behrend, is a fundamental tool in the Donaldson-Thomas theory. For the moduli space of coherent sheaves on a smooth Calami-Yau threefold, the Joyce-Song formula of Behrend function identities for the coherent sheaves are the essential part for the wall crossing of the counting invariants. In this talk I will talk about the motivic version of these formulas and their role in the wall crossing of motivic Donaldson-Thomas invariants.Seminar URL: https://research.math.osu.edu/agseminar/
