Brouwer’s fixed point theorem, in mathematics, a theorem of algebraic topology that was stated and proved in 1912 by the Dutch mathematician L.E.J. Brouwer. Inspired by earlier work of the French mathematician Henri Poincaré, Brouwer investigated the behaviour of continuous functions (see continuity) mapping the ball of unit radius in n ... WebMar 17, 2024 · Brouwer's theorem can be generalized to infinite-dimensional topological vector spaces. References Comments There are many different proofs of the Brouwer fixed-point theorem. The shortest and conceptually easiest, however, use algebraic topology. Completely-elementary proofs also exist. Cf. e.g. [a1], Chapt. 4.
