SEMINARI DI SISTEMI DINAMICI OLOMORFI

Terrà un seminario dal titolo:

"Generic hyperbolic properties of classical systems on the torus $T^2$"

 

Abstract:

 

One main problem in proving the existence of long diffusion orbitsfor perturbations of integrable systems in action-angle form is to understand the structure of generic classical systems on the torus $T^2$(this is the problem of transition at double resonances). We will prove the existence in such systems of chains of hyperbolic cylinders(one-parameter families of hyperbolic orbits) which realize fixed homology classes in projection on $T^2$, and we will discuss the problem of accumulation of such cylinders to homoclinic orbits of the hyperbolic fixed point of generic classical systems.

 

 

 

Tutti gli interessati sono invitati a partecipare.
