报告题目：An introduction to some recent results on nowhere-zero flows on signed Eulerian graphs

报告简介：This report focuses on some recent results in nowhere-zero flows on signed graphs. The main content of this report comes from the paper "NOWHERE-ZERO FLOWS ON SIGNED EULERIAN Graphs" by Máˇcajová et al. The contents of this report are as follows. First, we give some classic conclusions in integer flows. Second, we introduce flow-admissible signed graphs. Finally, we discuss nowhere-zero 4-flows on signed Eulerian graphs.
