Title: A Topological Proof of Van Der Waerden's Theorem

Abstract: Van Der Waerden's Theorem states that for a natural number k and any k-coloring of the natural numbers, some color class must contain arbitrarily long arithmetic progressions. In an effort to anger the ACO people, we will prove this using no combinatorics whatsoever. Instead, we will use topological semigroups, ultrafilters, and other abstract nonsense.
