On exponential dichotomy of semigroups
B. Sasu


Abstract.  The aim of this paper is to analyze the connections between the exponential dichotomy of a semigroup on a Banach space X and the admissibility of the pair (l p(N, X), q p(N, X)). We obtain necessary and sufficient conditions for exponential dichotomy of exponentially bounded semigroups using discrete time techniques.

Keywords: Semigroup of linear operators, exponential dichotomy.
