CF-modules over commutative rings

Comment.Math.Univ.Carolin. 59,1 (2018) 25-34.

Abstract:Let $R$ be a commutative ring with unit. We give some criterions for determining when a direct sum of two CF-modules over $R$ is a CF-module. When $R$ is local, we characterize the CF-modules over $R$ whose tensor product is a CF-module.

Keywords: CF-couple; CF-module; commutative ring; local ring
