Cohomological symmetry in triangulated categories

Petter Andreas Bergh, Steffen Oppermann

Published 2011-05-01Version 1

We give a criterion for cohomological symmetry in a triangulated category. As an application, we show that such cohomological symmetry holds for all pairs of modules over any exterior algebra.
