摘要

给定 G=(g1,⋯,gt),其中 gi∈N 为 1≤i≤t,让 GKs≤t 表示 s 个顶点上的非均匀完整超图,其边集包含 1≤i≤t 的顶点集的每个 i 子集的 gi 副本。让 Ks≤t 表示 1≤i≤t 时 gi=1 的 GKs≤t。最近,He 等人确定了所有 s,t,使得 Ks≤t 具有 1 因子化。在本手稿中,我们考虑了 GKs≤t 的 1 因式分解,并得到以下结果。(1) 若 2gt≥gj 为 1≤j≤t-1 且 s≡0(modt),则 GKs≤t 对于足够大的 s 具有 1 因式分解。

A note on the 1-factorization of non-uniform complete hypergraph

Given G=(g1,,gt) with giN for 1it, let GKst denote the non-uniform complete hypergraph on s vertices, whose edge set contains gi copies of every i-subset of vertex set for 1it. Let Kst denote GKst for gi=1 for 1it. Recently, He et al. determined all s,t such that Kst has a 1-factorization. In this manuscript, we consider the 1-factorization of GKst and obtain the following results. (1) If 2gtgj for 1jt1 and s0(modt), then GKst has a 1-factorization for sufficiently large s. (2) If GKst has a 1-factorization for sufficiently large s, then s0,1(modt).
