Abstract

In this paper, we prove the asymptotic multipartite version of the Alon-Yuster theorem, which is a generalization of the Hajnal-Szemer\'edi theorem: If k3k\geq 3 is an integer, HH is a kk-colorable graph and γ>0\gamma>0 is fixed, then, for every sufficiently large nn, where V(H)|V(H)| divides nn, and for every balanced kk-partite graph GG on knkn vertices with each of its corresponding (k2)\binom{k}{2} bipartite subgraphs having minimum degree at least (k1)n/k+γn(k-1)n/k+\gamma n, GG has a subgraph consisting of kn/V(H)kn/|V(H)| vertex-disjoint copies of HH. The proof uses the Regularity method together with linear programming.
