Title:
Renormalization of analytic maps of the circle and of the annulus
Speaker:
Abstract:
In a joint work with N. Goncharuk, we introduce a renormalization operator to study the problem of analytic linearization of holomorphic germs close to rigid rotations. This allows us to revisit the "classical" KAM theory for analytic maps of the circle and the annulus. As one consequence, we obtain a
