Motivic degree zero Donaldson-Thomas invariants
Kai Behrend, Jim Bryan, Balazs Szendroi
Given a smooth complex threefold X, we define the virtual motive of the Hilbert scheme of n points on X. In the case when X is Calabi-Yau, this gives a motivic refinement of the n-…

The Milnor fibre of the Pfaffian and the Hilbert scheme of four points on C^3
Alexandru Dimca, Balazs Szendroi
We study a natural Hodge module on the Hilbert scheme of four points on affine three-space, which categorifies the Donaldson--Thomas invariant of the Hilbert scheme. We determine t…
