%0 Journal Article %T Dual Bass Numbers and Co-Cohen Macaulay Modules %A Lingguang Li %J Mathematics %D 2010 %I arXiv %X In this paper, we give a characterization of co-Cohen Macaulay modules by vanishing properties of the dual Bass numbers of modules. In addition, we show that the co-localization of co-Cohen Macaulay modules preserves co-Cohen Macaulayness under a certain condition. %U http://arxiv.org/abs/1009.2229v5
