Abstract:

In this paper we give characterizations of the spectrum of a ${C_0}$-semigroup ${e^{At}}$ in terms of certain solution properties of the differential equation $(\ast )\;u’ = Au + f$ and, in case $X$ is a Hilbert space, also in terms of properties of ${(\lambda - A)^{ - 1}}$. We give several applications of these results including a study of the existence of dichotomic projections for $(\ast )$.
