Round table on current research and open problems

Chairman: Frank-Olme Speck

Abstract. Current development in the areas of research within the CEAF is exposed by corresponding representatives of the lines of investigation. New directions and open problems are emphasized in order to stimulate the progress, exchange of ideas and cooperation within the center. The session is open to all CEAF members and their collaborators. The order of presentations is:
1. A.F. dos Santos: Riemann-Hilbert Problems and Factorization,
2. M.A. Bastos: Operator Algebras and Index Theory,
