$C^n$-almost periodic and almost periodic solutions for some nonlinear integral equations
Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we investigate the existence of $C^n$-almost periodic solution for a class of nonlinear Fredholm integral equations, and the existence of almost periodic solution for a class of nonlinear functional integral equations.

Remotely Almost Periodic Solutions of Ordinary Differential Equations
Journal of Mathematics, 2021 In this paper, we analyze the existence and uniqueness of remotely almost periodic solutions for systems of ordinary differential equations. The existence and uniqueness of remotely almost periodic solutions are achieved by using the results about the ...

Journal of Harbin University of Science and Technology, 2019 Almost periodic solutions of differential equations are more general than periodic solutions, so almost periodic solutions will be studied on a class secondorder differential equations with piecewise constant argument.

Almost periodicity of solutions for almost periodic evolution equations
Differential and Integral Equations, 2005 In this paper, we discuss almost periodicity of solutions for evolution equations in Banach space. We introduce the concept of difference-variation equation. For a special Hilbert space, we establish some results on almost periodicity of all solutions for evolution equations. In particular, we extend Haraux's result on $R^2$ to $R^n.$

Almost periodic solutions of Volterra difference systems
Demonstratio Mathematica, 2017 We study the existence of an almost periodic solution of discrete Volterra systems by means of fixed point theory. Using discrete variant of exponential dichotomy, we provide sufficient conditions for the existence of an almost periodic solution.

Almost periodicand asymptotically almost periodic solutions of Liénard equations
Discrete and Continuous Dynamical Systems - B, 2011 The aim of this paper is to study the almost periodic and asymptotically almost periodic solutions on (0,+1) of the Li´enard equation x′′ + f(x)x′ + g(x) = F(t), where F : T ! R (T = R+ or R) is an almost periodic or asymptotically almost periodic function and g : (a, b) ! R is a strictly decreasing function.

Almost Periodic Viscosity Solutions of Nonlinear Parabolic Equations
Boundary Value Problems, 2009 We generalize the comparison result 2007 on Hamilton-Jacobi equations to nonlinear parabolic equations, then by using Perron's method to study the existence and uniqueness of time almost periodic viscosity solutions of nonlinear parabolic equations ...
