Many Turan exponents via subdivisions

Tao Jiang, Yu Qiu

Given a graph $H$ and a positive integer $n$ , the {\it Turán number} $\ex(n,H)$ is the maximum number of edges in an $n$ -vertex graph that does not contain $H$ as a subgraph. A rea…

Turan numbers of bipartite subdivisions

Tao Jiang, Yu Qiu

Given a graph $H$ , the Turán number $e x (n, H)$ is the largest number of edges in an $H$ -free graph on $n$ vertices. We make progress on a recent conjecture of Conlon, Janzer, and Le…

Some sharp results on the generalized Turán numbers

Jie Ma, Yu Qiu

For graphs $T, H$ , let $e x (n, T, H)$ denote the maximum number of copies of $T$ in an $n$ -vertex $H$ -free graph. In this paper we prove some sharp results on this generalization of T…
