Directed Graphs Conference

The main focus of the conference, to be held at the University of Waterloo, will be on Flows and MinMax equalities.

There have been recent exciting advances towards Tutte's famous 3-, 4-, and 5-flow conjectures. Extending Thomassen's breakthrough work, it is now known that the 3-flow conjecture (actually Jaeger's strengthening of it) holds for 6-edge-connected graphs. The entire conjecture would follow if the 6 could be replaced by 5.
