Nonstandard additively finite triangulated categories of Calabi-Yau dimension one in characteristic 3

Abstract

We prove that there exist nonstandard \(K\)-linear triangulated categories with finitely many indecomposable objects and Calabi-Yau dimension one over an arbitrary algebraically closed field \(K\) of characteristic \(3\), using deformed preprojective algebras of generalized Dynkin type.
