On the vanishing viscosity limit in a disk

We say that the solution u to the Navier-Stokes equations converges to a solution v to the Euler equations in the vanishing viscosity limit if u converges to v in the energy norm uniformly over a finite time interval. Working specifically in the unit disk, we show that a necessary and sufficient condition for the vanishing viscosity limit to hold is the vanishing with the viscosity of the time-space average of the energy of u in a boundary layer of width proportional to the viscosity due to modes (eigenfunctions of the Stokes operator) whose frequencies in the radial or the tangential direction lie between L and M. Here, L must be of order less than 1/(viscosity) and M must be of order greater than 1/(viscosity)

Exceptional Solutions of Hill Equations

AbstractA unified global classification of Hill equations summarizing classical and other results is presented. Connection between Lyapunov exponent and the rotation number of Hill equation is explained. It is shown that the notion of exceptional solutions introduced in [Elbert et al., Differential Integral Equations5 (1992), 945-960] is applicable to every Hill equation. A complete list of exceptional solutions for all Hill equations is given
