Brouwer's fixed point theorem applications
The Brouwer fixed-point theorem forms the starting point of a number of more general fixed-point theorems. The straightforward generalization to infinite dimensions, i.e. using the unit ball of an arbitrary Hilbert space instead of Euclidean space, is not true. The main problem here is that the unit balls of … See more Brouwer's fixed-point theorem is a fixed-point theorem in topology, named after L. E. J. (Bertus) Brouwer. It states that for any continuous function $${\displaystyle f}$$ mapping a compact convex set to itself there is a point See more The theorem has several formulations, depending on the context in which it is used and its degree of generalization. The simplest is sometimes given as follows: In the plane Every … See more The theorem has several "real world" illustrations. Here are some examples. 1. Take two sheets of graph paper of equal size with coordinate … See more The Brouwer fixed point theorem was one of the early achievements of algebraic topology, and is the basis of more general fixed point theorems which … See more The theorem holds only for functions that are endomorphisms (functions that have the same set as the domain and codomain) and for sets that are compact (thus, in particular, bounded and closed) and convex (or homeomorphic to convex). The following … See more Explanations attributed to Brouwer The theorem is supposed to have originated from Brouwer's observation of a cup of gourmet coffee.
