 Aleksandra Kwiatkowska (Department of Mathematics, University of Illinois at Urbana-Champaign)The pseudo-arc and its homeomorphism group, part 2Abstract: Continuing the talk by Slawomir Solecki on February 24, we further explore properties of the pseudo-arc and of its homeomorphism group. We plan to talk around the work of Oppenheim on the problem of the existence of a dense conjugacy class in the group of all homeomorphisms of the pseudo-arc. The projective Fraisse theory plays a crucial role in his work.
