On the maximum number of copies of H in graphs with given size and order

We study the maximum number $ex\left(n,e,H\right)$ of copies of a graph $H$ in graphs with a given number of vertices and edges. We show that for any fixed graph $H,ex\left(n,e,H\right)$ is asymptotically realized by the quasi‐clique provided that the edge density is sufficiently large. We also investigate a variant of this problem, when the host graph is bipartite.
