2-Calabi-Yau Categories Associated with
Coxeter Group Elements
ABSTRACT: This
is a joint work with Buan, Reiten, Scott and Smith. We study 2-CY
categories associated with preprojective algebras of non-Dynkin quivers
and elements in the corresponding Coxeter
groups. They contain cluster tilting objects associated with reduced
expressions. We shall show that the corresponding 2-CY tilted algebras
are given by quivers with rigid potentials.
