A module M is said auto invariant module if M invariant under automorphism of its injective envelope, i.e ?(M) ? M for every ? 2 AutR(E(M)). Every pseudo-injective module is auto invariant module. Dual notion of injective module is projective module. In similar way, the dual notion of auto invarian modul is called auto ko-invarian module. A module M is called auto ko-invarian module if whenever K1 and K2 are small submodules of M, then any small epimorphism ? : M=K1
