Title：An introduction to some recent results on nowhere-zero flows on signed Eulerian graphs

Abstract：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.

Speaker：Chao Wen, Ph.D., Guizhou University. His research interests include Algebra and graph theory. His results published on《Discrete Applied Mathematics》《Discrete Mathematics》.
