The present work of the book is devoted to the study of fixed point theorems in complete metric spaces, partially ordered metric spaces, complex valued metric spaces and fixed point iterative procedures. The book ends with an application of fixed point theory as fractal tiling and colour stealing from digital natural images. The book is divided into seven chapters. The first chapter is introductory in nature and presents some definitions, notions and fundamental preliminaries on fixed point theory, fixed point iterative procedures and fractal.
