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.

If f: Y → Y is a continuous function, then ϕ − 1 ∘ f ∘ ϕ: X → X is also continuous so it has a fixed point, say it x. You can easily check that ϕ ( x) is a fixed point of f.
