A construction of Gorenstein projective tau-tilting modules

Abstract

We give a construction of Gorenstein projective τ\tau-tilting modules in terms of tensor products of modules. As a consequence, we give a class of non-self-injective algebras admitting non-trivial Gorenstein projective τ\tau-tilting modules. Moreover, we show that a finite dimensional algebra Λ\Lambda over an algebraically closed field is CMCM-τ\tau-tilting finite if Tn(Λ)T_n(\Lambda) is CMCM-τ\tau-tilting finite which gives a partial answer to a question on CMCM-τ\tau-tilting finite algebras posed by Xie and Zhang.
