Toward a Hajnal-Szemeredi theorem for hypergraphs
arXiv:1005.4079
Abstract
Let be a triple system with maximum degree and let . Then has a proper vertex coloring with colors such that any two color classes differ in size by at most one. The bound on is sharp in order of magnitude apart from the logarithmic factors. Moreover, such an -coloring can be found via a randomized algorithm whose expected running time is polynomial in the number of vertices of $\cH$. This is the first result in the direction of generalizing the Hajnal-Szemerédi theorem to hypergraphs.
