Strict Mittag-Leffler conditions and locally split morphisms

Yanjiong Yang, Xiaoguang Yan (2018)

Czechoslovak Mathematical Journal

Similarity:

In this paper, we prove that any pure submodule of a strict Mittag-Leffler module is a locally split submodule. As applications, we discuss some relations between locally split monomorphisms and locally split epimorphisms and give a partial answer to the open problem whether Gorenstein projective modules are Ding projective.
