Abstract

Let Λ\Lambda be a finite dimensional algebra. In this paper we show that there is a natural bijection between cosilting modules in ModΛ\Lambda and semibricks in ModΛ\Lambda satisfying some condition. Also this bijection restricts to a bijection between all semibricks in modΛ\Lambda and a certain subclass of cosilting modules. These bijections are generalizations of Asai's correspondence [7] between support τ\tau^--tilting modules and right finite semibricks.
