Abstract

Let T(·) be a bounded C0-semigroup on the Banach space X, with generator A. It is shown that the denseness of range A is necessary and sufficient for the semigroup's mean stability with respect to suitable weights. Analogous results are valid for power bounded operators, tensor product semigroups, and cosine operator functions.
