Fluctuations of the nth return time for Axiom A diffeomorphisms
We study the time of $n$th return of orbits to some given
(union of) rectangle(s) of a Markov partition for an Axiom A
diffeomorphism. Namely, we prove the existence of a scaled
generating function for these returns with respect to any Gibbs
measure. As a by-product, we derive precise large deviation
estimates and a central limit theorem for these return times. We
emphasize that we look at the limiting behavior in term of number
of visits (the size of the visited set is kept fixed). Our
approach relies on the spectral properties of a one-parameter
family of induced transfer operators on unstable leaves crossing
the visited set.
