Abstract:

We investigate the statistical properties of a piecewise smooth dynamical system by directly studying the action of the transfer operator on appropriate spaces of distributions. We accomplish such a program in the case of two-dimensional maps with uniformly bounded second derivative. For the class of systems at hand, we obtain a complete description of the SRB measures, their statistical properties and their stability with respect to many types of perturbations, including deterministic and random perturbations and holes.

  • Additional Notes: The authors would like to thank the Institut Henri Poincaré where part of this work was done (during the trimester Time at Work). Also the authors enjoyed partial support from M.I.U.R. (Cofin 05-06 PRIN 2004028108). The first author was partially supported by NSF VIGRE Grant DMS-0135290 and by the School of Mathematics of the Georgia Institute of Technology. Finally, the second author would like to warmly thank G. Keller with whom, several years ago, he had uncountably many discussions on these types of problems. Although we were not able to solve the problem at the time, as the technology was not ripe yet, the groundwork we did has been precious for the present work.
