I append below an announcement that may be of interest to some readers of the categories list. Best, Pedro. ########### NEW JUNIOR RESEARCH POSITIONS IN MATHEMATICS AT IST The Center for Mathematical Analysis, Geometry, and Dynamical Systems of Instituto Superior Tecnico plans to open soon 4 research positions in mathematics in one of the areas in which the faculty of the Center is currently active, privileging the following: differential equations and dynamical systems (3 maximum); geometry and topology (including string theory and mathematical-physics) (3 maximum). All positions are for a period of 5 years, subject to annual evaluations. The Center is a research and scientific training unit of Instituto Superior Tecnico (http://www.ist.utl.pt/). It was established in 1991 and develops its activity in mathematics with special emphasis on nonlinear analysis, dynamical systems, geometry, and topology. The applicants should hold a Ph.D. in Mathematics or in a related area relevant to the scientific interests of the faculty of the Center, for at least 3 years. They must have a strong curriculum and show a very strong research promise. Details about these new positions and how to apply will be available soon in the Center's web page: http://camgsd.math.ist.utl.pt. The expected application deadline for this program is August 31st, 2007.
