Title: | Rings Over Which Flat Covers of Simple Modules Are Projective | Authors: | Büyükaşık, Engin | Keywords: | Flat covers Perfect ring Projective module |
Publisher: | World Scientific Publishing Co. Pte Ltd | Source: | Büyükaşık, E. (2012). Rings over which flat covers of simple modules are projective. Journal of Algebra and its Applications, 11(3). doi:10.1142/S0219498811005737 | Abstract: | Let R be a ring with identity. We prove that, the flat cover of any simple right R-module is projective if and only if R is semilocal and J(R) is cotorsion if and only if R is semilocal and any indecomposable flat right R-module with unique maximal submodule is projective. | URI: | http://doi.org/10.1142/S0219498811005737 http://hdl.handle.net/11147/6793 |
