 ibers and the logarithm law for Lorenz like flows. - Galatolo\, S (Univers

DESCRIPTION:A system satisfy a logarithm law if the time which is needed t
 o hit a small target scales as the inverse of the measure of the target.\n
 This kind of laws\, related to the occurrence of a rare event are also rel
 ated to the arithmetical properties and to the speed of mixing of the syst
 em.\nI will present a short introduction to the subject and show how a gen
 eral statement about the speed of convergence to equilibrium for systems w
 ith contracting fibers can be applied to deduce the logarithm law for a cl
 ass of  singular hyperbolic flows.\n\n
