On the Existence of Universal Graphs by Prof. Aaron Hill

Mathematics and Statistics Department Faculty Seminar by Prof. Aaron Hill, University of North Texas

Abstract:  We'll discuss infinite graphs and whether certain classes of infinite graphs (e.g. the class of countable graphs) have a universal element.  Interestingly, some of these questions require more than the usual axioms of ZFC to answer.  The talk should be fully accessible to those who know what a graph is (the sort of graph that has vertices and edges) and know basic facts about countability (e.g., that a countable union of countable sets is countable).
