Title:Generalized Hopf bifurcations
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Marc Chaperon, Jussieu
This is joint work with Santiago Lopez de Medrano (UNAM, Mexico). Following Thom's principle: "Always look for the organizing center of phenomena", we were able to prove a general "birth lemma" for families of dynamical systems at partially elliptic rest points; it implies the birth of normally hyperbolic compact invariant manifolds diffeomorphic to all kinds of moment-angle manifolds in generic families; these manifolds can form a family of matrioshkas, providing for example a very simple model for the transition between two periodic regimes.
