On Donaldson-Thomas invariants of threefold stacks and gerbes
Published 4 Jan 2010 in math.AG | (1001.0435v1)
Abstract: We present a construction of Donaldson-Thomas invariants for three-dimensional projective Calabi-Yau Deligne-Mumford stacks. We also study the structure of these invariants for etale gerbes over such stacks.
