Maximum cliques in a graph without disjoint given subgraph

Fangfang Zhang, Yaojun Chen, Ervin Gyori +1

The generalized Turán number $\ex(n,K_s,F)$ denotes the maximum number of copies of $K_{s}$ in an $n$ -vertex $F$ -free graph. Let $k F$ denote $k$ disjoint copies of $F$ . Gerbner, Meth…

Extremal problems for a matching and any other graph

Xiutao Zhu, Yaojun Chen

For a family of graphs $\F$, a graph is called $\F$-free if it does not contain any member of $\F$ as a subgraph. The generalized Turán number $\ex(n,K_r,\F)$ is the maximum number…

A new construction for planar Turán number of cycle

Ervin Győri, Kitti Varga, Xiutao Zhu

The planar Turán number $ex_{P} (n, C_{k})$ is the largest number of edges in an $n$ -vertex planar graph with no cycle of length $k$ . Let $k \geq 11$ and $C, D$ be constan…
