Abstract:
      In this paper, we prove a generalization of Schauder′s fixed point theorem for discontinuous maps. The main result shows that for discontinuous functions on a compact convex domain X of a Banach spaces E, one can always find a point x∈X such that |x-f(x)| is less than a certain measure of discontinuity. This result is a generalization of Schauder′s theorem and .
