This paper consists of results on contraction semigroups thereby considering ω-order reversing partial contraction mapping (semigroup of linear operator)
as the infinitesimal generator of the semigroup on perturbation by bounded linear operators which we will show that the addition of a bounded linear operator B to an infinitesimal generator A of a semigroup of linear opearator does not destroy the property of A.
