Brouwer’s Approximate Fixed-Point Theorem is Equivalent to Brouwer’s Fan TheoremIn a weak system for intuitionistic analysis, one may prove, using the Fan Theorem as an additional axiom, that, for every continuous function ? from the unit square U to itself, for every positive rational e, there exists x in U such that |?(x) ? x| < e. Conversely, if this statement is taken as an additional axiom, the Fan Theorem follows.
