# Textbooks or notes on gradient flows in metric spaces.

What is a good introduction in gradient flows in metric spaces? I know the book Gradient flows: in metric spaces and in the space of probability measures by Luigi Ambrosio, Nicola Gigli and Giuseppe Savaré, but is too hard for an introduction (for me). I'm looking for something with a similar content.

But this is a hard topic. A new one indeed. I doubt that there be any easier book on this subject. –  Denis Serre Oct 21 '10 at 19:06
Maybe someone has written lecture notes about this subject, it doesn't have to be a book. –  Jonas Teuwen Oct 21 '10 at 19:18
