Abstract: Patterson-Sullivan distributions were introduced by Anantharman and Zelditch [AZ07] in the setting of
hyperbolic surfaces and generalizde to compact higher rank locally symmetric spaces by Hansen, Hilgert
and Schr ̈oder [HHS12]. In both cases they were introduced as Quantum Phase space distributions. More
recently it has been worked out (using a quantum classical correspondence) that on rank one locally
symmetric spaces Patterson-Sullivan distributions coincide with invariant Ruelle distributions [GHW21].
This correspondance led to high frequency limits of Ruelle distributions as well as to generalized Residue
formulas for Patterson-Sullivan distributions [SWB23].
