Smooth dynamics via Operators, with Singularities
ERC AdG SOS (2018-2023)
Transfer operators applied to hyperbolic systems
with low regularity including billiards
(rates of mixing, linear or fractional response Ruelle resonances, susceptibility function etc.)
This project has received funding from the European Research Council (ERC) under
the European Union's Horizon 2020 research and innovation programme (grant
agreement No 787304)
