Title: Resonances for shear flows and complex deformation

Abstract: 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 deformation of the interval on which the Rayleigh equation is considered. We show such resonances are inviscid limits of the eigenvalues of the corresponding Orr–Sommerfeld equation. We present examples for which the viscous perturbations of resonances are unstable. Joint work with Malo Jézéquel.
