WebEarly in his career, Brouwer proved a number of theorems in the emerging field of topology. The most important were his fixed point theorem, the topological invariance of degree, and the topological invariance of … WebMay 24, 2016 · In dimension two the Brouwer Fixed-Point Theorem states that every continuous mapping taking a closed disc into itself has a fixed point. In this chapter we’ll give a proof of this special case of Brouwer’s result, but for triangles rather than discs; closed triangles are homeomorphic to closed discs (Exercise 2.2 below) so our result will …
Web1978] THE BROUWER FIXED POINT THEOREM 523 First Proof. Let the region A considered above be defined by the inequalities 1/2 < lIxii < 3/2.

In discrete mathematics, a discrete fixed-point is a fixed-point for functions defined on finite sets, typically subsets of the integer grid . Discrete fixed-point theorems were developed by Iimura, [1] Murota and Tamura, [2] Chen and Deng [3] and others. Yang [4] provides a survey.
