These lectures have been given in the framework of the PDE seminar organized by N. Alikakos at the University of Athens, in room A31, Departement of Mathematics. Friday May 9th, 3pm-4.15pm Friday May 16th, 3pm-4.15pm Friday May 30th, 3pm-3.50pm Friday June 6th, 3pm-4.15pm During the weeks between Lectures 1 and 2 and between Lectures 3 and 4 I was kindly hosted by the Departement (office 110, first floor, or in Nick's office). |

A short reference, with almost no proofs, for Lectures 1-3 is given by the Lecture Notes for a Summer School held in Grenoble in 2009 (to be published now by Cambridge Univ. Press).

I also have a project of a book, an evolution from the above lecture notes and from some notes I wrote for a course (20h) that I gave at Orsay in 2011 and 2012. You can have a look here, it is still in progress. Lecture 1 corresponds to a large part of Chapter 1, and Lecture 2 of Chapter 5. The last two lectures discussed part of Chapters 7 and 8.
