Abstract

The main purpose of this paper is to find the conditions for the Minimal Horse-Shoe Lemma to be hold in some categories of graded modules. Using the Minimal Horse-Shoe Lemma, we prove that the category of p- Koszul modules is closed under direct sums, direct summands, extensions and cokernels.
