Hypergraph Turan with bounded matching number

Yue Xu, Jiasheng Zeng, Xiao-Dong Zhang

For a fixed graph $G$ , an $r$ -uniform hypergraph is said to contain a Berge- $G$ if there exists a bijection $f : E (G) \to E (H)$ for some subhypergraph $H$ su…

Generalized Turan number with given size

Yan Wang, Yue Xu, Jiasheng Zeng +1

Generalized Turán problem with given size, denoted as $mex (m, K_{r}, F)$ , determines the maximum number of $K_{r}$ -copies in an $F$ -free graph with $m$ edges. We prove that for…

Dense halves in balanced 2-partition of K4-free graphs

Yue Xu, Xiao-Dong Zhang

A balanced 2-partition of a graph is a bipartition $A, A^{c}$ of $V (G)$ such that $∣ A ∣ = ∣ A^{c} ∣$ . Balogh, Clemen, and Lidický conjectured that for every $K_{4}$ -free graph on $n$ (even) ve…
