Finitistic Dimension of Faithfully Flat Weak Hopf-Galois Extension

Aiping Zhang

Let $H$ be a finite-dimensional weak Hopf algebra over a field $k$ and $A / B$ be a right faithfully flat weak $H$ -Galois extension. We prove that if the finitistic dimension of $B$ …

Finitistic dimension and Endomorphism algebras of Gorenstein projective modules

Aiping Zhang

Let $A$ be an Artin algebra, $M$ be a Gorenstein projective $A$ -module and $B =$ End $_{A} M$ , then $M$ is a $A$ - $B$ -bimodule. We use the restricted flat dimension of $M_{B}$ to give a…
