In this thesis,we discuss the existence of almost periodic type solutions to some class of nonlinear integral equations.In chapter 1,we introduce the background of the thesis and the main problems studied in the thesis.In chapter 2,we introduce the basic definitions,properties and theorems that are relevant to this thesis.In chapter 3,we prove the existence of almost periodic and pseudo almost solutions for a nonlinear integro-differential equation with neutral delay(?).In chapter 4,by using Avery-Henderson and Leggett-Williams fixed point theorems on cones,we obtain that the existence theorems of multiple almost periodic solutions for a class of nonlinear integral equation(?). |
