$r$ -cross $t$ -intersecting families via necessary intersection points

Pranshu Gupta, Yannick Mogge, Simón Piga +1

Given integers $r \geq 2$ and $n, t \geq 1$ we call families $F_{1}, \dots, F_{r} \subseteq P ([n])$ $r$ -cross $t$ -intersecting if for all $F_{i} \in F_{i}$ ,…

On extremal problems concerning the traces of sets

Simón Piga, Bjarne Schülke

Given two non-negative integers $n$ and $s$ , define $m (n, s)$ to be the maximal number such that in every hypergraph $H$ on $n$ vertices and with at most $m (n, s)$ edges t…

Localised codegree conditions for tight Hamilton cycles in 3-uniform hypergraphs

Pedro Araújo, Simón Piga, Mathias Schacht

We study sufficient conditions for the existence of Hamilton cycles in uniformly dense $3$ -uniform hypergraphs. Problems of this type were first considered by Lenz, Mubayi, and Myc…
