1968年,Vizing证明了任意边色临界图G =(V,E)的最大度△和独立数α(G),α(G)≤(|V|本文证明了α(G)≤(3△-3)/(5△-3)|V|对△ ∈ {9,10}和α(G)≤(15△-42)/(23△-42)|V|对于△∈{11,.,46}.
In 1968,Vizing conjectured for any edge chromatic critical graph G =(V,E) with maximum degree △ and independence number α(G),α(G)≤(|V|)/2.In this paper,we proved that α(G)≤(3△-3)/(5△-3)|V| for △ ∈ {9,10} and α(G)≤(15△-42)/(23△-42)|V| for △∈{11,…,46}.
