Abstract

We study how many copies of a graph FF that another graph GG with a given number of cliques is guaranteed to have. For example, one of our main results states that for all t2t\ge 2, if GG is an nn vertex graph with kn3/2kn^{3/2} triangles and kk is sufficiently large in terms of tt, then GG contains at least Ω(min{ktn3/2,k2t23t1n5t23t1})\Omega(\min\{k^t n^{3/2},k^{\frac{2t^2}{3t-1}}n^{\frac{5t-2}{3t-1}}\}) copies of K2,tK_{2,t}, and furthermore, we show these bounds are essentially best-possible provided either kn1/2tk\ge n^{1/2t} or if certain bipartite-analogues of well known conjectures for Tur\'an numbers hold.
