DESCRIPTION:\n Ruelle resonances are complex numbers associated to a dynam
ical system that describe the precise asymptotics of the correlations for
large times. It is well known that this notion makes sense for smooth unif
ormly hyperbolic dynamics on compact manifolds. In this talk\, I will cons
ider the case of the geodesic flow on some noncompact manifolds. In a clas
s of such manifolds (called SPR)\, I will explain that one can define Ruel
le resonances in a half-plane delimited by a critical exponent at infinity
. Joint work with Barbara Schapira and Samuel Tapie.\n\n\n================
