Title: Nash-Williams Orientation Conjecture for Infinite Graphs       

Speaker: Amena Assem Affiliation University of Waterloo Location: MC 5479

Abstract: In 1960 Nash-Williams proved that every 2k-edge-connected finite graph admits a k-arc-connected orientation. He conjectured that this is  also true for infinite graphs. We try to prove the conjecture. Joint work with Bruce Richter.
