Tilting modules and support $\tau$-tilting modules over preprojective algebras associated with symmetrizable Cartan matrices

Changjian Fu, Shengfei Geng

For any given symmetrizable Cartan matrix $C$ with a symmetrizer $D$, Geiß~ et al. (2016) introduced a generalized preprojective algebra $\Pi (C,D)$. We study tilting modules and sup…
