In 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. Some authors claim that results of this kind are amongst the most generally useful in mathematics.

WebApr 8, 2024 · Given an action of a group on some space, and given a point or (or more generally some subspace), then the stabilizer group of that point (that subspace) is the subgroup whose action leaves the point (the subspace) fixed, invariant.
WebApr 11, 2024 · This paper will first explore fixed point theory, including the Kakutani Fixed Point Theorem and Brouwer Fixed Point Theorem; fixed point theorems are a significant field of mathematics and have many well-known applications. One of these applications is game theory, which is the study of how rational actors make decisions in everyday … A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is mapped to itself by the function.
