Victoria Rayskin received her Ph.D. in Mathematics from the University of California at Berkeley, focusing on Dynamical Systems. She has been working in the fields of Banach spaces and smooth extension of maps, Ergodic Theory and Dynamical Systems.
Jointly with Genrich Belitskii, Rayskin developed a new approach for smooth localization of maps on Banach spaces. They applied this technique for smooth linearization in a neighborhood of a fixed point—a convenient simplification of dynamical systems. Together with Boris Hasselblatt and Misha Guysinsky, Rayskin proved existence of linearization in lower classes of smoothness for maps with resonances, and later obtained some generalizations for Banach spaces (with Belitskii).
