Counting stable sheaves on singular curves and surfaces
Amin Gholampour
Given a quasi-projective scheme M over complex numbers equipped with a perfect obstruction theory and a morphism to a nonsingular quasi-projective variety B, we show it is possible…

Donaldson-Thomas invariants, linear systems and punctual Hilbert schemes
Amin Gholampour, Artan Sheshmani
We study certain DT invariants arising from stable coherent sheaves in a nonsingular projective threefold supported on the members of a linear system of a fixed line bundle. When t…

Degeneracy loci, virtual cycles and nested Hilbert schemes II
Amin Gholampour, Richard P. Thomas
We express nested Hilbert schemes of points and curves on a smooth projective surface as "virtual resolutions" of degeneracy loci of maps of vector bundles on smooth ambient spaces…
