This is just a short note to tell you that I haven’t quit thinking about mathematics. I was in the process of writing up the report when I hit upon the subject of calculus in America. There I got stuck and still is. So instead, I took time off to prepare for a research workshop in Florence in Italy (Higher Spins, Strings and Duality) . I’m going there in April. I’ll be away for 4 weeks. But before that the report must be finished and I’ll soon be back writing here!
