Abstract

In this paper we Proved other properties of essential and complement submodules to an arbitrary submodule of an R-module M .We prove that for a family {Mα}α ∊ʌ of modules . If Tα and Nα are submodules of Mα with N α +T α ≤T α-e M α ,∀ α, then ⨁α∊ʌ (Nα +Tα)≤⨁ α ∊ʌ Tα –e ⨁α ∊ʌ Mα. Also we show that for submodules T, A, B and C of a module M such that T ≤ A ≤ C. If B is T- c for A in M and C is T- c for B in M , then C is maximal T- essential extension of A in M
