Properties of resonant states for generic smooth expanding maps

Malo Jézéquel, Malo Jézéquel

We prove that the resonances for a generic smooth expanding map are simple and that zero is a regular value for the associated resonant states. Moreover, the real-valued resonant s…

Bound on the number of Ruelle resonances for Gevrey hyperbolic flows

Malo Jézéquel

We improve the best known upper bounds on the number of Ruelle resonances in disks of large radius for Gevrey uniformly hyperbolic flows. The proof is based on Rugh's approach of d…

Stationary internal waves in a two-dimensional aquarium at low viscosity

Malo Jézéquel, Jian Wang

We prove the uniform solvability of a stationary problem associated to internal waves equation with small viscosity in a two dimensional aquarium with real-analytic boundary, under…

Orr-Sommerfeld equation and complex deformation

Malo Jézéquel, Jian Wang

For shear flows in a 2D channel, we define resonances near regular values of the shear profile for the Rayleigh equation under an analyticity assumption. This is done via complex d…

Zeta functions and the Fried conjecture for smooth pseudo-Anosov flows

Malo Jézéquel, Malo Jézéquel, Jonathan Zung

To a transitive pseudo-Anosov flow on a -manifold and a representation of , we associate a zeta function defined for , generalizing…

Distribution of Ruelle resonances for real-analytic Anosov diffeomorphisms

Malo Jézéquel

We prove an upper bound for the number of Ruelle resonances for Koopman operators associated to real-analytic Anosov diffeomorphisms: in dimension , the number of resonances lar…
