-FP-Projective Modules and Dimensions
Let R be a ring and let S be a multiplicative subset of R . An R -module M is said to be a u - S -absolutely pure module… Click to show full abstract
Let be a ring and let be a multiplicative subset of . An -module is said to be a --absolutely pure module if is --torsion for any finitely presented -module . This paper introduces and studies the notion of -FP-projective modules, which extends the classical notion of FP-projective modules. An -module is called an -FP-projective module if for any --absolutely pure -module . We also introduce the -FP-projective dimension of a module and the global -FP-projective dimension of a ring. Then, the relationship between the -FP-projective dimension and other homological dimensions is discussed.
