Crawley-Boevey and Sauter have shown that Auslander algebras have such tilting modules; and for algebras of global dimension $2$, Auslander algebras are classified by the existence of such tilting modules. In this …

In this article we investigate the relations between the Gorenstein projective dimensions of -modules and their socles for minimal n-Auslander-Gorenstein algebras in the sense of Iyama and Solberg \cite {IS}. First we give a description of projective-injective -modules in terms of their socles.

We say that a finite-dimensional restricted Lie algebra has maximal 0-PIM if this maximal possible dimension is attained (see Section 2). One main goal of the paper is then to classify all finite-dimensional restricted Lie algebras having maximal 0-PIM.
