 Maps in minimal injective resolutions of modules Bull. Korean Math. Soc. 2009 Vol. 46, No. 3, 545-551 https://doi.org/10.4134/BKMS.2009.46.3.545Printed May 1, 2009 Kisuk Lee Sookmyung Women's University Abstract : We investigate the behavior of maps in minimal injective resolution of an $A$-module $M$ when $\mu_t(\frak m,M)$ = 1 for some $t$, and we develop slightly the fact that a module of type 1 is Cohen-Macaulay. Keywords : Bass numbers, minimal injective resolutions, type of modules, Cohen-Macaulay rings MSC numbers : 13H10, 13C14, 13D02 Downloads: Full-text PDF
