A Lefschetz duality intersection homology

Published 13 Dec 2010 in math.AT | (1012.2695v2)

Abstract: We prove a Lefschetz duality result for intersection homology. Usually, this result applies to pseudomanifolds with boundary which are assumed to have a "collared neighborhood of their boundary". Our duality does not need this assumption and is a generalization of the classical one.
