If you have a question about this talk, please contact Mustapha Amrani. Moduli Spaces On a manifold there is the graded algebra of polyvector fields with its Lie-Schouten bracket, and the module of de Rham differentials with exteriour differentiation. This package is called a “calculus”. The moduli space of sheaves (or derived category objects) on a Calabi-Yau threefold has a kind of “virtual calculus” on it. In particular, this moduli space has virtual de Rham cohomology groups, which categorify Donaldson-Thomas invariants, at least conjecturally. We describe some attempts at constructing such a virtual calculus. This is work in progress. This talk is part of the Isaac Newton Institute Seminar Series series.
