n-th Order Functional Problems with Resonance of Dimension One

Mathematics, 2021
We consider the nonlinear n-th order boundary value problem Lu=u(n)=f(t,u(t),u′(t),…,u(n−1)(t))=Nu given arbitrary bounded linear functional conditions Bi(u)=0, i=1,…,n and develop a method that allows us to study all such resonance problems of order one,

The existence of almost periodic solution: via coincidence degree theory [PDF]

Boundary Value Problems, 2016
The author studies the existence of an almost periodic solution of a delay differential equation. First, few important lemmas are established and then the main result is proved. The main technique used is topological degree theory. Several estimates are established in order to fit the system in the framework of degree theory.
