Flows on flow-admissible signed graphs
نویسندگان
چکیده
In 1983, Bouchet proposed a conjecture that every flow-admissible signed graph admits nowhere-zero 6-flow. himself proved such graphs admit 216-flows and Zýka further 30-flows. this paper we show 11-flow.

Nowhere-zero flows on signed regular graphs
We study the flow spectrum S(G) and the integer flow spectrum S(G) of odd regular graphs. We show that there are signed graphs where the difference between the integer flow number and the flow number is greater than or equal to 1, disproving a conjecture of Raspaud and Zhu [7]. Let G be a (2t + 1)-regular graph. We show that if r ∈ S(G), then r = 2 + 1t or r ≥ 2 + 2 2t−1 . This result generaliz...
متن کاملVector Flows in Graphs and Integer Flows in Signed Graphs
My research focuses on the flow problems consisting of two parts, vector flows in graphs and integer flows in signed graphs. The concept of integer flows was first introduced by Tutte (1949) as a refinement of map coloring. In fact, integer flows is the dual concept of map coloring for planar graphs. This is often referred as duality theorem. Tutte proposed three celebrated flow conjectures whi...
متن کاملNowhere-Zero 3-Flows in Signed Graphs
Tutte observed that every nowhere-zero k-flow on a plane graph gives rise to a kvertex-coloring of its dual, and vice versa. Thus nowhere-zero integer flow and graph coloring can be viewed as dual concepts. Jaeger further shows that if a graph G has a face-k-colorable 2-cell embedding in some orientable surface, then it has a nowhere-zero k-flow. However, if the surface is nonorientable, then a...
متن کاملResolution of indecomposable integral flows on signed graphs
It is well-known that each nonnegative integral flow of a directed graph can be decomposed into a sum of nonnegative graph circuit flows, which cannot be further decomposed into nonnegative integral sub-flows. This is equivalent to saying that indecomposable flows of graphs are those graph circuit flows. Turning from graphs to signed graphs, the indecomposable flows are much richer than that of...
متن کاملClassification of Conformally Indecomposable Integral Flows on Signed Graphs
A conformally indecomposable flow f on a signed graph Σ is a nonzero integral flow that cannot be decomposed into f = f1 + f2, where f1, f2 are nonzero integral flows having the same sign (both ≥ 0 or both ≤ 0) at every edge. This paper is to classify at integer scale conformally indecomposable flows into characteristic vectors of Eulerian cycle-trees — a class of signed graphs having a kind of...
