In this paper, the notion of soft Jacobson radical a ring is defined. A relationship between and semisimple established. Some properties have been studied under homomorphism.

We describe the representation theory of finitely generated indecomposable modules over artin algebras which do not lie on cycles involving homomorphisms from infinite Jacobson radical module category.
