Dear all, A PSSL will be organized by the University of Utrecht (in the Netherlands) in the weekend of the 28th and 29th of June. I will launch a webpage where the necessary information can be found. You will be informed as soon as it is finished. With best regards, Benno -- Benno van den Berg - Mathematisch Instituut, UU vdberg@math.uu.nl - P.O.box 80.010, 3508 TA Utrecht, NL
