Abstract

This paper is concerned with the existence of global limit solutions for the quasi–nonlinear functional evolution problem

where A(t, ψ1) and G(t, ψ1, Ltψ2) are defined, with respect to ψ1, on a subspace of the space PC([–r, 0], X) of all piecewise continuous functions ƒ : [–r, 0] → X. An appropriate subspace of PC([–r, t], X) is the domain of definition of the nonlinear operators Lt, t ∈ [0, T]. The operators A(t, ψ)x are w-dissipative and Lipschitz — like in (t, ψ) which are more general conditions than those of Karsatos–Liu. The operators G and Lt are Lipschitzian mappings on their respective domains. Moreover, we investigate the uniqueness and strong solution for such problem.
