## Abstract

Using the Lubell function, we are able to generalize the notion of Turan density for non-uniform hypergraphs. We will give proofs of some generalizations of classical results, including: the supersaturation lemma and the fact that blowing-up doesn't change the Turan density. We also completely characterize the Turan density for certain families of hypergraphs. The talk will include a lot of examples - with pictures - and proofs of some of the main theorems. This is joint work with Lincoln Lu.
