Complete subgraphs in a multipartite graph

Allan Lo, Andrew Treglown, Yi Zhao

In 1975 Bollobás, Erd\H os, and Szemerédi asked the following question: given positive integers $n, t, r$ with $2 \leq t \leq r - 1$ , what is the largest minimum degree $δ (G)$ among all…

Shadows of 3-uniform hypergraphs under a minimum degree condition

Zoltán Füredi, Yi Zhao

We prove a minimum degree version of the Kruskal--Katona theorem: given $d \geq 1/4$ and a triple system $F$ on $n$ vertices with minimum degree at least $d (2 n)$ , we obtain asym…
