Matching stability for 3-partite 3-uniform hypergraphs

Hongliang Lu, Xinxin Ma

Let $n, k, s$ be three integers such that $k \geq 2$ and $n \geq s \geq 1$ . Let $H$ be a $k$ -partite $k$ -uniform hypergraph with $n$ vertices in each class. Aharoni (2017) showed that i…

A characterization on $(g, f)$ -parity orientations

Hongliang Lu, Xinxin Ma

Let $G$ be a graph and $g, f : V (G) \to 2^{N}$ be two set functions such that $g (v) \leq f (v)$ and $g (v) \equiv f (v) (mod 2)$ for every $v \in V (G)$ . An orientation $O$ of $G$ is called a $(g,…
