Abstract

This paper is a continuous work of “Y. Pan, Weakly discrete
Koszul modules, submitted, (2011)” ([12]), where the so-called weakly discrete
Koszul module was first introduced. In this paper, the Ext module of
a weakly discrete Koszul module is studied. Further, as the application of
the approximation chain theorem obtained in [12], we will study the relations
of the minimal graded projective resolutions between a given weakly discrete
Koszul module and its quotients.

Keywords
