Existence of Exotic rotation domains and Herman rings for quadratic Hénon maps
Raphaël Krikorian
A quadratic Hénon map is an automorphism of $\C^2$ of the form . It has a constant Jacobian equal to and has two fixed points. If is…

Coexistence of ac and pp spectrum for kicked quasi-periodic potentials
Kristian Bjerklöv, Raphaël Krikorian
We introduce a class of real analytic "peaky" potentials for which the corresponding quasi-periodic 1D Schrödinger operators exhibit, for quasiperiodic frequencies in a set of posi…
