An Extension of De Giorgi Class and Applications

Hongya Gao, Aiping Zhang, Siyu Gao

We present an extension of the classical De Giorgi class, and then we show that functions in this new class are locally bounded and locally Hölder continuous. Some applications are…

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…
