Generalized Andrásfai--Erdős--Sós theorems for odd cycles

Zian Chen, Jianfeng Hou, Caiyun Hu +1

In this note, we establish Andrásfai--Erdős--Sós-type stability theorems for two generalized Turán problems involving odd cycles, both of which are extensions of the Erdős Pentagon…

Many vertex-disjoint even cycles of fixed length in a graph

Jianfeng Hou, Caiyun Hu, Heng Li +3

For every integer $k \geq 3$ , we determine the extremal structure of an $n$ -vertex graph with at most $t$ vertex-disjoint copies of $C_{2 k}$ when $n$ is sufficiently large and $t$ l…
