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.
