摘要

The aim of this paper is to study the two-sided remotely almost periodic solutions of ordinary differential equations in Banach spaces of the form \(x'=A(t)x+f(t)+F(t,x)\) x ′ = A ( t ) x + f ( t ) + F ( t , x ) with two-sided remotely almost periodic coefficients if the linear equation \(x'=A(t)x\) x ′ = A ( t ) x satisfies the condition of exponential trichotomy and nonlinearity F is "small".
