A note on the 1-factorization of non-uniform complete hypergraph
Given with for , let denote the non-uniform complete hypergraph on s vertices, whose edge set contains copies of every i-subset of vertex set for . Let denote for for . Recently, He et al. determined all such that has a 1-factorization. In this manuscript, we consider the 1-factorization of and obtain the following results. (1) If for and , then has a 1-factorization for sufficiently large s. (2) If has a 1-factorization for sufficiently large s, then .
