Stratifications of algebras with two simple modules

Representation Theory 2014-06-16 v2

Abstract

Let AA be a finite-dimensional algebra with two simple modules. It is shown that if the derived category of AA admits a stratification with simple factors being the base field kk, then AA is derived equivalent to a quasi-hereditary algebra. As a consequence, if further kk is algebraically closed and AA has finite global dimension, then AA is either derived simple or derived equivalent to a quasi-hereditary algebra
