Simple-minded systems and reduction for negative Calabi-Yau triangulated categories

Representation Theory 2018-08-09 v1

Abstract

We develop the basic properties of ww-simple-minded systems in (w)(-w)-Calabi-Yau triangulated categories for w1w \geq 1. The main result is a reduction technique for negative Calabi-Yau triangulated categories. We show that the theory of simple-minded systems exhibits striking parallels with that of cluster-tilting objects. Our construction provides an inductive technique for constructing simple-minded systems.
