Integral Biflow Maximization

Guoli Ding, Rongchuan Tao, Mengxi Yang +1

Let $G = (V, E)$ be a graph with four distinguished vertices, two sources $s_{1}, s_{2}$ and two sinks $t_{1}, t_{2}$ , let $c : E \to Z_{+}$ be a capacity function, and let ${\c…

A short proof of the Goldberg-Seymour conjecture

Guantao Chen, Yanli Hao, Xingxing Yu +1

For a multigraph $G$ , $χ^{'} (G)$ denotes the chromatic index of $G$ , $Δ (G)$ the maximum degree of $G$ , and $Γ(G) = \max\left\{\left\lceil \frac{2|E(H)|}{|V(H)|-1} \right\rceil: H \sub…
