On a conjecture of Hefetz and Keevash on Lagrangians of intersecting hypergraphs and Turán numbers

Biao Wu, Yuejian Peng, Pingge Chen

Let $S^{r} (n)$ be the $r$ -graph on $n$ vertices with parts $A$ and $B$ , where the edges consist of all $r$ -tuples with $1$ vertex in $A$ and $r - 1$ vertices in $B$ , and the sizes of $…

Dense $3$ -uniform hypergraphs containing a large clique

Biao Wu, Yuejian Peng

An $r$ -uniform graph $G$ is dense if and only if every proper subgraph $G^{'}$ of $G$ satisfies $λ (G^{'}) < λ (G)$ , where $λ (G)$ is the Lagrangian of a hypergraph $G$ . In 1980's, Sidorenk…
