Query: An equivalence between Frobenius algebras and Calabi-Yau categories   We show that the bigroupoid of separable symmetric Frobenius algebras over an
algebraically closed field and the bigroupoid of finitely semi-simple
Calabi-Yau categories are equivalent. To this end, we construct a trace on the
category of finitely-generated representations of a symmetric, separable
Frobenius algebra, given by the composite of the Frobenius form with the
Hattori-Stallings trace. In order to put this result into perspective, we
introduce the concept of the equivariantization of a 2-functor between
bicategories endowed with a G-action. We prove that the equivalence between
Frobenius algebras and Calabi-Yau categories is actually the equivariantization
of the 2-functor sending a separable algebra to its category of
finitely-generated modules, where we endow both the bicategory of algebras,
bimodules and intertwiners and the bicategory of linear categories with the
trivial SO(2)-action and take homotopy fixed points as considered in [HSV16].
