摘要

证明了代数闭域上半简单对称Frobenius代数的双群似形与Calabi-Yau范畴的双群似形是等价的。为此，我们在对称的半简单Frobenius代数的有限生成表示范畴上构造了一条迹，由Frobenius形式与Hattori-Stallings迹的复合给出。

An equivalence between semisimple symmetric Frobenius algebras and Calabi–Yau categories

We show that the bigroupoid of semisimple symmetric Frobenius algebras over an algebraically closed field and the bigroupoid of Calabi–Yau categories are equivalent. To this end, we construct a trace on the category of finitely-generated representations of a symmetric, semisimple Frobenius algebra, given by the composite of the Frobenius form with the Hattori-Stallings trace.
