Abstract

Let R be a commutative ring with identity. We call the proper submodule N of
M a coquasi - invertible submodule if (M, N)  0
Hom(M,N)  0
Hom the main purpose of this
work is the study of the properties of coquasi - invertible submodules. and give
definithon of corational submodule. Then show that if M is self projective, then N
is coquasi - invertible submodule of M if and only if N is corational in M
