Pancyclicity of graphs perturbed by a random $F$ -factor

Dingjia Mao, Feihong Yuan, Wenling Zhou

We determine the sharp minimum-degree threshold for Hamiltonicity in graphs perturbed by a uniformly random $K_{r}$ -factor, resolving a conjecture of Espuny Díaz and Girão [Random St…

A local spectral condition for perfect matchings in 3-graphs

Huiqiu Lin, Hongliang Lu, Feihong Yuan +1

Let $γ$ be a constant such that $0 < γ < 1$ , and let $n$ be a sufficiently large integer. Consider a $3$ -uniform hypergraph $H$ on $n$ vertices. In 2013, Kühn, Osthus, and Treglown,…

Rainbow matchings in edge-colored graphs

Hongliang Lu, Zixuan Yang, Feihong Yuan

Let $G$ be an edge-colored graph. We use $e (G)$ and $c (G)$ to denote the number of edges and colors in $G$ , respectively. A subgraph $H$ is called rainbow if $c (H) = e (H)$ . Li et al.…
