报告摘要：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 the relation between modulo flows and signed graphs and flows of signed graphs without long barbells.
