Stability of generalized Turán number for linear forests

Yisai Xue, Yichong Liu, Liying Kang

Given a graph $T$ and a family of graphs $F$ , the generalized Turán number of $F$ is the maximum number of copies of $T$ in an $F$ -free graph on $n$ v…

On a conjecture of spectral extremal problems

Jing Wang, Liying Kang, Yusai Xue

For a simple graph $F$ , let $Ex (n, F)$ and $E x_{sp} (n, F)$ denote the set of graphs with the maximum number of edges and the set of graphs with the maximum spectra…

Solution to a Forcible Version of a Graphic Sequence Problem

Mao-cheng Cai, Liying Kang

Let $A_{n} = (a_{1}, a_{2}, \dots, a_{n})$ and $B_{n} = (b_{1}, b_{2}, \dots, b_{n})$ be nonnegative integer sequences with $A_{n} \leq B_{n}$ . The purpose of this note is to give a good characterization such t…

Spectral extremal graphs for intersecting cliques

Dheer Noal Desai, Liying Kang, Yongtao Li +3

The $(k, r)$ -fan is the graph consisting of $k$ copies of the complete graph $K_{r}$ which intersect in a single vertex, and is denoted by $F_{k, r}$ . Erdős, Füredi, Gould and Gunderso…

The extremal $p$ -spectral radius of Berge-hypergraphs

Liying Kang, Lele Liu, Linyuan Lu +1

Let $G$ be a graph. We say that a hypergraph $H$ is a Berge- $G$ if there is a bijection $ϕ : E (G) \to E (H)$ such that $e \subseteq ϕ (e)$ for all $e \in E (G)$ . For any $r$ -uniform hyper…

The largest spectral radius of uniform hypertrees with a given size of matching

Li Su, Liying Kang, Honghai Li +1

In this paper, using the theory of matching polynomial of hypertrees and ordering of hypertrees, we determine the largest spectral radius of hypertrees with $m$ edges and given siz…
