Total convergence or general divergence in Small Divisors
We study generic holomorphic families of dynamical systems presenting
problems of small divisors with fixed arithmetic. We prove that we have
convergence for all parameter values or divergence everywhere except for an
exceptional set in the potential theory sense. We illustrate this general
principle in different problems of small divisors
Ergodic solenoids and generalized currents
We introduce the concept of solenoid as an abstract laminated space. We do a
thorough study of solenoids, leading to the notion of ergodic and uniquely
ergodic solenoids. We define generalized currents associated with immersions of
oriented solenoids with a transversal measure into smooth manifolds,
generalizing Ruelle-Sullivan currents.Comment: 28 pages, 2 figures. Fully revised presentation of the paper.
