Chapter-1 Introduction to integral equations

Abstract

"There is a vital role of differential and integral equations in studying different types of real-world problems to study the behavior of the issues. Thus, it becomes essential to know the various methods of finding solutions of the integral equation in explicit form. For the integral equations whose solutions cannot be found in explicit form, one has to study the properties of solutions of the given differential equation to guess an approximate solution. This textbook entitled “Applied Integral Equations” is intended to study the methods of finding the explicit solutions of integral equations where ever possible and in the absence of finding an exact solution. It is intended to study the properties of solutions of the given integral equations. This book contains 08 chapters. Chapter-1 discusses the introduction to integral equations, classification of integral equations, Relation between linear differential equations and Volterra integral equation, Nonlinear equation and solution of an integral equation. Chapter-2 discusses the existence and uniqueness theorems of Integral equations,Successive approximation, Iterated Functions, Reciprocal functions, Volterra Solution of Fredholm’s equation, Discontinuous Solution, Fredholm equations with separable kernels and Resolvent Kernel. Chapter-3 discusses the Fredholm equation as a limit of a finite system of linear equations,
