本文证明了Alon-Yuster定理的渐近多部形式,它是Hajnal-Szemerédi定理的推广:如果k≥ 3是整数,H是k-可着色图,γ> 0是固定的,那么,对任何充分大的n,其中|V(高)|除n,且对每个kn阶平衡k-部图G,其对应的(k2)个二部子图的最小度至少为(k-1)n/k+ γ n,则G有一个由kn/|V(高)|H的顶点不相交副本。证明使用正则性方法和线性规划。
In this paper, we prove the asymptotic multipartite version of the Alon–Yuster theorem, which is a generalization of the Hajnal–Szemerédi theorem: If k≥ 3 is an integer, H is a k-colorable graph and γ> 0 is fixed, then, for every sufficiently large n, where| V (H)| divides n, and for every balanced k-partite graph G on kn vertices with each of its corresponding (k 2) bipartite subgraphs having minimum degree at least (k− 1) n/k+ γ n, G has a subgraph consisting of k n/| V (H)| vertex-disjoint copies of H. The proof uses the Regularity method together with linear programming.
