© 2017 Elsevier B.V. If for a vector space V of dimension g over a characteristic zero field we denote by ∧iV its alternating powers, and by V∨ its linear dual, then there are natural Poincaré isomorphisms: ∧iV∨≅∧g−iV. We describe an analogous result for objects in rigid pseudo-abelian Q-linear ACU tensor categories.
