It has been a while since I last wrote here. I might as well restart matters with a brief update.

Summer was full of activities and travel. After giving a course at the summer school on analytic number theory at IHES, I went to Korea for most of August (ANTS and of course the ICM). Then I went back to Paris and got the keys to my new office at IMJ (Paris VI/VII), where I will be from now on as a CNRS *Directeur de recherche*. The office is in the Paris VII campus, close to the Bibliothèque Nationale and, most importantly, the Cinémathèque.

… and then I left for Saint Petersburg, to spend a trimester there as a Lamé Chair. During that time, I was offered a Humboldt Professorship (at Göttingen) , which I am now considering.

I have been back in Paris since late December, after relatively brief trips to Perú and the Czech Republic. I also managed to lose the keys to my office in the interval. It took a very long time to get another set of keys.

On a different note – my survey paper on growth in groups got accepted; it is about to appear. I also spent a great deal of time rewriting my proof of the Ternary Goldbach Conjecture – it is now in an essentially self-contained monograph. Besides adding expository material, I simplified some parts of the proof – notably the part on parabolic cylinder functions.

I have some partial drafts of planned blog posts from the last few months. Let me include here a brief set of impressions from my Korea trip. I did this in French, just to keep my chops up.
