Fixed point theory is one of the most important branches of mathematics. Fixed point theory is divided into topological fixed point theory, metric fixed point theory and discrete fixed point theory. These divisions are based on the three classical theorem, known as Brouwer's fixed point theorem, Banach's fixed point theorem and Tarski's fixed point theorem. Fixed point theorems are essentially used for solving a given equation which in turn may be reduced to finding the fixed points of certain
