Characteristic determinants for a second order difference equation on the half-line arising in hydrodynamics

Yuri Latushkin, Shibi Vasudevan

We study the point spectrum of a second order difference operator with complex potential on the half-line via Fredholm determinants of the corresponding Birman-Schwinger operator p…

Instability of unidirectional flows for the 2D Navier-Stokes equations and related $α$ -models

Shibi Vasudevan

We study instability of unidirectional flows for the linearized 2D Navier-Stokes equations on the torus. Unidirectional flows are steady states whose vorticity is given by Fourier…

Instability of unidirectional flows for the 2D $α$ -Euler equations

Holger Dullin, Yuri Latushkin, Robert Marangell +2

We study stability of unidirectional flows for the linearized 2D $α$ -Euler equations on the torus. The unidirectional flows are steady states whose vorticity is given by Fourier mo…
