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