(HoRSe seminar) Hilbert schemes of threefolds: virtual motives, Hodge modules and deformed MacMahon formulae II
I will talk about joint work with Dimca, respectively Behrend and Bryan, in which we refine the numerical DT-Behrend invariants of Hilbert schemes of threefolds by using vanishing cycle motives (a la Kontsevich-Soibelman) or mixed Hodge modules, leading to deformed MacMahon formulae.
