Intersection homology with field coefficients: $K$-Witt spaces and $K$-Witt bordism

Geometric Topology 2011-03-31 v2 Algebraic Topology

Abstract

We construct geometric examples of pseudomanifolds that satisfy the Witt condition for intersection homology Poincare duality with respect to certain fields but not others. We also compute the bordism theory of KK-Witt spaces for an arbitrary field KK, extending results of Siegel for K=QK=Q.
