Set Theoretic Topology Seminar
Time: Sep 12, 2016 (03:00 PM)
Location: Parker Hall 246


Speaker: David Lipham

David continues from last week. He will finish the proof of his example, and discuss some related open questions.

Abstract. A widely-connected set is a connected set that is irreducible between every two of its points.

The object of this paper is the construction of widely-connected subsets of the plane. We give a completely metrizable example that answers a question of Paul Erdős and Howard Cook. A similar example answers a question of Jerzy Mioduszewski.
