Abstract
Let (Tt) be a strongly continuous semigroup of bounded linear operators on a Banach space X, satisfying equation omited. We prove the equivalence of the following conditions: (1) t-1 equation omited converges uniformly as t → ∞. (2) The infinitesimal generator A has closed range. (3) Equation omitedexists in the uniform operator topology.
