Poincar\'e duality isomorphisms in tensor categories

Category Theory 2014-09-08 v1

Abstract

If for a vector space V of dimension g over a characteristic zero field we denote by iV\wedge^iV its alternating powers, and by VV^\vee its linear dual, then there are natural Poincar\'e isomorphisms: iVgiV\wedge^i V^\vee \cong \wedge^{g-i} V. We describe an analogous result for objects in rigid pseudo-abelian Q\mathbb{Q}-linear ACU tensor categories.
