Abstract:
We study linear operators T on Banach spaces for which there exists a C0-semigroup (T(t))t≥0 such that T = T(1). We present a necessary condition in terms of the spectral value 0 and give classes of examples for which such a C0-semigroup does or does not exist. Received: 22 December 2008, Revised: 7 April 2009
