Semibricks and Brick-finite algebras

Let $Λ$ be a finite-dimensional algebra. Using the kappa order on the lattice of torsion classes with canonical join representations, we obtain an equivalent condition for $Λ$ to b…

Semibrick-cosilting correspondence

Ramin Ebrahimi, Alireza Nasr-Isfahani

Let $Λ$ be a finite dimensional algebra. In this paper we show that there is a natural bijection between cosilting modules in Mod $Λ$ and semibricks in Mod $Λ$ satisfying some condit…
