Tóm tắt:

A module M is called an essentially injective module if for every submodule A of N, any homomorphism f : A → M with essential kernel can be extended to N. In this talk, we study on basic results of essentially injective modules. In particular, the invariant of essentially injective modules via injective envelope are obtained. Keywords: essentially injective module, nonsingular ring.
