题    目:Flows of Signed Graphs


摘    要: Bouchet conjectured that every flow admissible signed graph admits a nowhere-zero integer 6-flow.  This conjecture is still widely open. In this talk I will present some recent progresses on flows of signed graphs. Specifically, I will talk about (1) the relation between modulo flows and signed graphs, (2) flows of signed graphs without long barbells, (3) an 11-flow theorem.
