Strong chromatic index of bipartite graphs

Yanli Hao, Tianchi Yang, Xingxing Yu

An edge-coloring of a graph $G$ is called a strong edge-coloring if all its color classes are induced matchings in $G$ ; the minimum number of colors required for such a coloring, d…

A class of trees determined by their chromatic symmetric functions

Yuzhenni Wang, Xingxing Yu, Xiao-Dong Zhang

Stanley introduced the concept of chromatic symmetric functions of graphs which extends and refines the notion of chromatic polynomials of graphs, and asked whether trees are deter…

Planar Turán number of the 7-cycle

Ruilin Shi, Zach Walsh, Xingxing Yu

The $planar Tur a ˊ n number$ $ex_{P} (n, H)$ of a graph $H$ is the maximum number of edges in an $n$ -vertex planar graph without $H$ as a subgraph. Let $C_{\e…

Linkages and removable paths avoiding vertices

Xiying Du, Yanjia Li, Shijie Xie +1

We say that a graph $G$ is $(2, m)$ -linked if, for any distinct vertices $a_{1}, \dots, a_{m}, b_{1}, b_{2}$ in $G$ , there exist vertex disjoint connected subgraphs $A, B$ of $G$ such that $\…

On stability of rainbow matchings

Hongliang Lu, Yan Wang, Xingxing Yu

We show that for any integer $k \geq 1$ there exists an integer $t_{0} (k)$ such that for integers $t, k_{1}, \dots, k_{t + 1}, n$ with $t > t_{0} (k)$ , $max {k_{1}, \dots, k_{t + 1}} \leq k$ , and…

Co-degree threshold for rainbow perfect matchings in uniform hypergraphs

Hongliang Lu, Yan Wang, Xingxing Yu

Let $k$ and $n$ be two integers, with $k \geq 3$ , $n \equiv 0 (mod k)$ , and $n$ sufficiently large. We determine the $(k - 1)$ -degree threshold for the existence of a rainbow perfect ma…
