A partition theorem for perfect sets

Author:

Blass Andreas

Abstract

Let P P be a perfect subset of the real line, and let the n n -element subsets of P P be partitioned into finitely many classes, each open (or just Borel) in the natural topology on the collection of such subsets. Then P P has a perfect subset whose n n -element subsets lie in at most ( n 1 ) ! (n - 1)! of the classes.
