Dear colleagues, I am happy to announce that a new Foundation called "Sciences Mathematiques de Paris" has just been created: www.sciencesmaths-paris.fr It groups several major laboratories of Paris in the field of mathematics, as well as the two computer science laboratories of Paris 7 University (LIAFA, www.liafa.jussieu.fr, and PPS, www.pps.jussieu.fr). The foundation will launch a number of programs. For this coming academic year (2007/2008), the following programs may be relevant for computer scientists interested to spend some time in Paris and wish to work in LIAFA or PPS: - a postdoc program (deadline for application: May 4th) - an invitation program for scientists for visits of 2 to 3 months (deadline for application: May 18th)
