    • Abstract


      In this paper, we establish some left and right multiplicative perturbation theorems concerning local 𝐶-semigroups when the generator 𝐴 of a perturbed local 𝐶-semigroup $S(\cdot)$ may not be densely defined and the perturbation operator 𝐵 is a bounded linear operator from $\overline{D(A)}$ into 𝑅(𝐶) such that $CB=BC$ on $\overline{D(A)}$, which can be applied to obtain some additive perturbation theorems for local 𝐶-semigroups in which 𝐵 is a bounded linear operator from $[D(A)]$ into $R(C)$ such that $CB=BC$ on $\overline{D(A)}$. We also show that the perturbations of a (local) 𝐶-semigroup $S(\cdot)$ are exponentially bounded (resp., norm continuous, locally Lipschitz continuous, or exponentially Lipschitz continuous) if $S(\cdot)$ is.
