Challenges

  1. Show that Banach's Fixed-Point Theorem (Parts I and II) actually holds on closed sets, even if unbounded. You cannot use the a priori existence of p in this case, since Brouwer's Fixed-Point Theorem does not hold.
  2. Show that all norms are equivalent on Rn. Proceed in two steps: first, show that any norm is a continuous function with respect to the maximum norm. Second, consider this norm on the unit sphere (the sphere for the maximum norm) and apply what you know about continuous functions.
