Ricardo Pérez-Marco

Ricardo Pérez- Marco (born 1967 in Barcelona) is a Spanish- French mathematician.

Pérez- Marco studied ( after preparation for study at the French Grand Ecoles at the Lycée Louis -le- Grand in Paris) at the Ecole Normale Superieure ( and the same physics in Barcelona) and his doctorate in 1990 at the University of Paris-Sud in Jean- Christophe Yoccoz ( linearization of germes de diffeomorphismes holomorphic de (C, 0) of the diffeomorphismes analytiques et du cercle ). After that, he was research director of CNRS, University of Paris XIII. He's since the early 2000s, a professor at the University of California, Los Angeles ( UCLA).

Pérez- Marco deals with dynamical systems and solved there several important problems, for which he received the 1996 EMS prize. Among other things, he solved a problem of Vladimir Arnold on the linearizability of analytic diffeomorphisms of the circle without accumulation points of periodic orbits. He developed a theory of analytic non- linearisierbarer germs.
