Nowhere-zero 8-flows in 3-edge-connected signed graphs
Matt DeVos, Kathryn Nurse, Robert Šámal
In 1983, A. Bouchet extended W.T. Tutte's notion of nowhere-zero flows to signed graphs, and conjectured that every flow-admissible signed graph has a nowhere-zero 6-flow. In this…

Many flows in the group connectivity setting
Matt DeVos, Rikke Langhede, Bojan Mohar +1
Two well-known results in the world of nowhere-zero flows are Jaeger's 4-flow theorem asserting that every 4-edge-connected graph has a nowhere-zero $\mathbb{Z}_2 \times \mathbb{Z}…

Cycle-continuous mappings -- order structure
Robert Šámal
Given two graphs, a mapping between their edge-sets is cycle-continuous, if the preimage of every cycle is a cycle. The motivation for this notion is Jaeger's conjecture that for e…
