Аннотация: This joint work with Z. Zhao (Nice) is concerned with the geometry of germs of real analytic surfaces in In this talk we focus on perturbations of hyperbolic quadrics. As was shown by Moser–Webster, such a surface can be transformed to a formal normal form by a formal change of coordinates that may not be holomorphic in any neighborhood of the origin. Given a non-degenerate real analytic surface This is a consequence of a non-standard KAM-like theorem for pair of germs of holomorphic involutions Язык доклада: английский |
