Abstract

Let (T(t))t0(T(t))_{t\geq 0} be a C0C_0 semigroup on a Banach space XX with infinitesimal generator AA. In this work, we give conditions for which the spectral mapping theorem σ(T(t))\{0}={eλs,λσ(A)}\sigma_{*}(T(t))\backslash \{0\}=\{e^{\lambda s}, \lambda\in\sigma_{*}(A)\} holds, where σ\sigma_* can be equal to the essential, Browder and Kato spectrum. Also, we will be interested in the relations between the spectrum of AA and the spectrum of the nth derivative T(t)(n)T(t)^{(n)} of a differentiable C0C_0 semigroup (T(t))t0(T(t))_{t\geq0}.
