Charles Morgan: Extent : density

Tuesday, December 6, 16.30. Mathematical Institute, University of Bonn, room 0.003 Charles Morgan: Extent : density Abstract: Extent and density are two classical properties of topological spaces. I shall discuss how their relationship is affected by (set theoretic) combinatorics for certain classes of spaces, and highlight the set theoretic problems brought into focus by the investigation. continue reading…
