报告题目:Flows of Signed Graphs

报 告 人:罗荣 教授

报告时间:201963(周一)  16:00-17:00

报告地点:磬苑校区数学科学学院H306

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.
