WebFixed point theory serves as an essential tool for various branches of mathematical analysis and its applications. Loosely speaking, there are three main approaches in this theory: the metric, the topological and the order-theoretic approach, where representative examples of these are: Banach's, Brouwer's and arski'sT theorems respectively.

WebIn mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F ( x) = x ), under some conditions on F that can be stated in general terms.
