On T- oplus-Supplemented Modules

Let be any preradical and M any module. In [2], Al-Takhman,Lomp and Wisbauer dened -supplemented module. In this paper we introducethe (completely) T-supplemented modules. It is shown that (1) Any -nite direct sum of T-supplemented modules is T-supplemented. (2) If M isT-supplemented module and (D3) then M is completely T-supplemented.
