Signed Graphs: From Modulo Flows to Integer-Valued Flows
Signed Graphs: From Modulo Flows to Integer-Valued Flows
Converting modulo flows into integer-valued flows is one of the most critical steps in the study of integer flows. Tutte and Jaeger's pioneering work shows the equivalence of modulo flows and integer-valued flows for ordinary graphs. However, such equivalence no longer holds for signed graphs. This motivates us to study …
