Abstract

A C0-semigroup S(t), t > 0, on a Banach space X (weakly, strongly, uniformly) approaches balanced (or asynchronous) exponential growth if there exists some s R such thatexists (in the weak, strong, uniform operator topology) and P is not the 0 operator. In this paper, the strong and uniform approach to balanced exponential growth is characterized and applicable sufficient conditions are derived. The results will be applied to models for age-size-structured population dynamics in a forthcoming publication. Copyright 1998 Academic Press.
