Donaldson-Thomas invariants for complexes on abelian threefolds

Martin G. Gulbrandsen

Published 2011-11-03Version 1

We modify the standard perfect symmetric obstruction theory for moduli spaces of simple perfect complexes, to the situation of complexes on abelian threefolds with fixed determinant and Fourier-Mukai determinant. As outcome we attach nontrivial Donaldson-Thomas invariants to moduli spaces for complexes modulo twist and translation.
