On Left Permitivity over a Matrix Ring’s and Module’s

Abstract: Aim of this paper a ring R be an associative ring with identity and all modules are unitary nR and ( )J R are denotes the matrix rings and Jacobson radical and the singular left ideal of R, also  be maximal left ideal of R , if R is left primitive, )0(e is idempotent in R then eRe is left primitive.
