Abstract
Essentially injectivity is a generalization of ojectivity.The concept of essentially injective module was presented.It was proved that essentially injective modules and essentially ojective modules were consistent.Similarly to the injective module,some properties of essentially injective modules,such as Baer Criterion were established.
