Özet
A module M is called E9-delta 88-supplemented if every submodule X of M has a delta 88-supplement Y in M which is a direct summand of M such that X + Y = M and X n Y Soco(Y) where Soco(Y) is the sum of simple and delta-small submodules of Y and M = Y E9 Y ' for some Y ' M. Moreover, M is called a completely E9-delta 88-supplemented module if every direct summand of M is E9-delta 88-supplemented. Thus, we present two new types of algebraic structures which are stronger than delta-D11 and delta-D+11-modules, respectively. In this paper we investigate basic properties, decompositions and ring characterizations of these modules.
