Grothendieck-Verdier functors
Max Demirdilek
We introduce Grothendieck-Verdier functors between Grothendieck-Verdier, or -autonomous, categories. Such functors are lax monoidal functors equipped with a morphism expressi…

Linearly distributive coherence in the absence of units
Max Demirdilek, Christian Reiher, Christoph Schweigert
Coherence in a monoidal category asserts that all morphisms built from structural isomorphisms with a fixed source and target coincide. These structural isomorphisms include, in pa…

Surface Diagrams for Frobenius Algebras and Frobenius-Schur Indicators in Grothendieck-Verdier Categories
Max Demirdilek, Christoph Schweigert
Grothendieck-Verdier categories (also known as -autonomous categories) generalize rigid monoidal categories, with notable representation-theoretic examples including categori…
