Abstract We prove a generalization of Brouwer's famous fixed point theorem to discontinuous maps. The main result shows that for discontinuous functions on a compact convex domainX one can always find a pointx ∈X such that ∥x−f(x)∥ is less than a certain measure of discontinuity. Applications to artificial neural nets, economic equilibria and analysis are given.
