摘要
本文的主要结果是:G=(A,B;E)是一偶图,|A|=|B|=n≥2,(x,y)∈E,有d(x)+d(y)≥n+1,且x1∈A,y0,y1∈B,(x0≠x1,y0≠y1),{x0,y0),(x1,y1)}∩E=φ,有d(x0)+d(x1)+d(y0)+d(y1)≥(8n+5)/3,则对G的任意独立边集M,G有含M的圈.
The main result in this paper is as follows: Let G= (A, B; E) be abipareite graph with 2n vertires. If, have dG(x)+dG(y)≥n + 1 and x1 ∈ A, y0, y1 ∈B, (x0≠x1, y0≠y1) {x0, y0), (x1, y2)} ∩ E = φ, dG(x0)+dG(x1)+dG (y0)+dG(y1)≥(8n+5)/3, then there exists a cirtuit in duding M, where M is a set of independent edges.
