AbstractIn thiswork,we provide sufficient conditions ensuring the existence and uniqueness of an Eberlein weakly almost periodic solutions for some semilinear integro-differential equations with infinite delay in Banach spaces. For illustration, we provide an example arising in viscoelasticity theory.

We consider abstract differential equations of the formu′(t)=Au(t)+f(t)oru″(t)=Au(t)+f(t)in Banach spacesX, wheref(⋅),ℝ→Xis almost-periodic, whileAis a linear operator,𝒟(A)⊂X→X. If the solutionu(⋅)is likewise almost-periodic,ℝ→X, we establish connections between their Bohr-transforms,uˆ(λ)andfˆ(λ).
