Özet

In this article, we focus on modules with the property that every projection invariant submodule is essential in a fully invariant direct summand. In contrast to -extending condition, it is shown that the former property is inherited by direct summands and Morita invariant. An application of our results yields that the endomorphism ring of a free module enjoys the property. Moreover, we characterize generalized triangular matrix rings with the aforementioned property and apply to somewhat special cases.
