Title: Gromov's Theorem: Asymptotic cones and the proof of the theorem
We discuss ultrafilters, ultrapowers, and asymptotic cones. Then we recall the notion of Hausdorff dimension, Tits' alternative theorem, the Montgomery-Zippin theorem. We complete with a detail account of all steps of the proof of the theorem.
