随机图的完全二部图分解

Decomposition of random graphs into complete bipartite graphs

Fan Chung, Xing Peng

摘要:

本文考虑图$G$的边集的最小划分问题,即边不相交的完全二部子图的最小个数为$τ(G)$。我们证明了对于随机图$G$在$G(n,p)$中,对于$p$是不大于$1/2$的常数,对于任何正的常数$c$和$ε$,几乎必然$τ(G)$在$n- c(\ln_{1/p} n)^{3+ε}$和$n - 2\ln_{1/(1-p)} n$之间。

英文摘要:

We consider the problem of partitioning the edge set of a graph $G$ into the minimum number $τ(G)$ of edge-disjoint complete bipartite subgraphs. We show that for a random graph $G$ in $G(n,p)$, for $p$ is a constant no greater than $1/2$, almost surely $τ(G)$ is between $n- c(\ln_{1/p} n)^{3+ε}$ and $n - 2\ln_{1/(1-p)} n$ for any positive constants $c$ and $ε$.
