The Koszul dual of a weakly Koszul module
[摘要] We study the so-called weakly Koszul modules and characterise their Koszul duals. We show that the (adjusted) associated graded module of a weakly Koszul module exactly determines the homology modules of the Koszul dual. We give an example of a quasi-Koszul module which is not weakly Koszul. (c) 2007 Elsevier Inc. All rights reserved.
