Carlangelo Liverani (Roma Uni): Locating Ruelle resonances
Abstract:
Ruelle resonances can be expressed either in terms of the Laplace
transform of the correlation functions or as point spectrum of the
Ruelle Transfer operator. While the first point of view is closer
to what can be measured observing the system, the latter is much
more efficient for the mathematical investigation. Unfortunately,
there are no general techniques to identify precisely the point
spectrum. I will present an approach that can provide some
information and can be applied in a variety of hyperbolic
dynamical systems. The approach is not really new, as traces of
it can be found already in Ruelle"s original work, yet it appears
that it was never explored or presented systematically.
