Brouwer's Fixed Point Theorem for Arbitrary Intervals

  1. Mar 28, 2010 #1
    Is it possible to prove Brouwer's Fixed Point Theorem (one-dimensional version) for intervals other than [-1,1]-->[-1,1], say [1,2]-->[0,3]? If so, how?

    For example, f(x)=x-1 is a map from [1,2] to [0,3] with no fixed point. The condition that the domain and codomain are the same space is very important
