本文用Bollobás和Komlós证明了以下猜想:对于每一个γ > 0和整数r≥1和Δ,存在具有以下性质的β > 0。如果G是一个足够大的图,有n个顶点,最小度至少为((r−1)/r + γ)n, H是一个r色图,有n个顶点,带宽最多为βn,最大度最多为Δ,则G包含H的一个副本。
In this paper we prove the following conjecture by Bollobás and Komlós: For every γ > 0 and integers r ≥ 1 and Δ, there exists β > 0 with the following property. If G is a sufficiently large graph with n vertices and minimum degree at least ((r − 1)/r + γ)n and H is an r-chromatic graph with n vertices, bandwidth at most βn and maximum degree at most Δ, then G contains a copy of H.
