Discrete Analysis

In this talk we will discuss recent results of M. Ostrovskii about embeddings of graphs into graphs of bounded degree and Lipschitz embeddings of expanders. Then we will show how we can adapt his construction to prove that there exists a family of expander graphs whose coarse Lipschitz embedding (a.k.a quasi-isometric embedding) into a Banach space forces the target space to have trivial cotype. One wants to mention that the proof does not require a ``metric cotype approach’’ and uses only classical Banach space theory.
