Concentration Theorem and Non-coarse Embeddability into Group Extensions

Abstract:

I will talk about expanders and their concentration theorems for different target spaces. And naturally these concentration theorems imply the non-coarse embeddability into corresponding target spaces. Also I will give another application of concentration theorems for the non-coarse embeddability into certain group extensions.
