ON THE ASYMPTOTIC EQUIVALENCE OF LINEAR DELAY EQUATIONS IN BANACH SPACE

DANG DINH CHAU

pp. 31-38

Abstract

In this paper we present some sufficient conditions for the asymptotic equivalence of linear evolution equations with time-delay in Banach spaces. Besides, we discuss the asymptotic relationship between $C_0$ groups and strongly continuous evolutionary processes. The obtained results extend the Levinsons theorem on the asymptotic equivalence of linear differential equations.
