Abstract

We identify additional structure on a conservative lax monoidal functor from a closed monoidal category C\mathcal{C} to a Grothendieck-Verdier category D\mathcal{D}, such that the Grothendieck-Verdier structure of D\mathcal{D} lifts to C\mathcal{C} and the functor becomes Frobenius linearly distributive. As an application, we recover and extend conditions under which modules over Hopf monads and Hopf algebroids inherit Grothendieck-Verdier structures. We also characterize when categories of bimodules, modules, and local modules over (commutative) algebras internal to a Grothendieck-Verdier category admit such structures. Our results apply to quantales, smash product algebras, skew group algebras, and enveloping algebras of Lie-Rinehart algebras. For applications of the lifting theorem, we construct a strict 22-equivalence between a 22-category of Grothendieck-Verdier categories and one of linearly distributive categories with negation, and extend this 22-equivalence to the braided setting.
