The aim of this book is to present a clear and well-organized treatment of the concept behind the development of mathematics and solution techniques. The main aim of this monograph is to study existence of multiple fixed points for some operators that are of the form T + F, where T is an expansive operator and F is a k-set contraction. The monograph offers the reader an overview of recent developments of multiple fixed point theorems and their applications.
