On support $\tau$-tilting modules over blocks covering cyclic blocks

Representation Theory 2020-04-28 v1

Abstract

Support τ\tau-tilting modules correspond to some classes of categorical objects bijectively, such as two-term tilting complexes for any finite dimensional symmetric algebra. This fact motivates us to classify support τ\tau-tilting modules over blocks of finite groups. Therefore we classify support τ\tau-tilting modules over particular blocks of finite groups by using the modular representation theoretical approaches including Clifford theory, Green's indecomposability theorem and so on.
