Abstract:

We explain how the computation of motivic Donaldson-Thomas invariants associated to a quiver with potential reduces to the computation of the motivic classes of simpler quiver varieties.  This has led to the calculation of these invariants for some interesting Calabi-Yau geometries derived equivalent to a quiver with potential. Here we observe q-deformations of the classical generating series.
