Nondegenerate Turán problems under $(t, p)$ -norms

Wanfang Chen, Daniel Iľkovič, Jared León +2

Given integers $r > t \geq 1$ and a real number $p > 0$ , the $(t, p)$ -norm $∥ H ∥_{t, p}$ of an $r$ -graph $H$ is the sum of the $p$ -th power o…

Strong stability from vertex-extendability and applications in generalized Turán problems

Wanfang Chen, Xizhi Liu

Extending the work of Liu--Mubayi--Reiher~\cite{LMR23unif} on hypergraph Turán problems, we introduce the notion of vertex-extendability for general extremal problems on hypergraph…
