Maximum spread of $K_{s, t}$ -minor-free graphs II: the non-admissible cases

William Linz, Linyuan Lu, Zhiyu Wang

We have previously determined the maximum-spread $K_{s, t}$ -minor-free graph(s) on $n$ vertices when $n$ is sufficiently large, $2 \leq s \leq t$ , and $s = 2$ or $t\ge \frac{3}{2}(s-3) +…

Some exact and asymptotic results for hypergraph TurÃ¡n problems in $ℓ_{2}$ -norm

George Brooks, William Linz

For a $k$ -uniform hypergraph $H$ , the \emph{codegree squared sum} $co_{2} (H)$ is the square of the $ℓ_{2}$ -norm of the codegree vector of $H$ , a…

Maximum spread of $K_{s, t}$ -minor-free graphs

William Linz, Linyuan Lu, Zhiyu Wang

The spread of a graph $G$ is the difference between the largest and smallest eigenvalue of the adjacency matrix of $G$ . In this paper, we consider the family of graphs which contai…
