Spectral extremal problems for the $(p, Q)$ -spectral radius of hypergraphs

Jian Zheng, Honghai Li, Li Su

Let $Q$ be an $s$ -vertex $r$ -uniform hypergraph, and let $H$ be an $n$ -vertex $r$ -uniform hypergraph. Denote by $N (Q, H)$ the number of isomorphic copies of $Q$ in $H$ . Fo…

Spectral TurÃ¡n-type problems for the $I^\pm$ -spectral radius of hypergraphs with degree stability

Jian Zheng, Honghai Li, Li Su

An $r$ -pattern $P$ is an ordered pair $P = ([l], E)$ , where $l$ is a positive integer and $E$ is a set of $r$ -multisets with elements from $[l]$ . An $r$ -graph $H$ is said to be $P$ -co…

A signless Laplacian spectral ErdÃ¶s-Stone-Simonovits theorem

Jian Zheng, Honghai Li, Li Su

The celebrated ErdÅs--Stone--Simonovits theorem states that $ex (n, F) = (1 - \frac{1}{I ¨ ( F ) - 1} + o (1)) \frac{n ^{2}}{2}$ , where $I ¨ (F)$ is the chromatic number of $F$ . I…
