Preprint: A Pseudo-Wavelet Scheme for Navier-Stokes Equations

Abstract: Numerical schemes taking advantage of the wavelet bases
capabilities to compress both functions and operators are presented.
Galerkin methods for the heat and Poisson equations in dimension two
are developed and numerically tested. Then a pseudo-wavelet scheme,
using collocation for the nonlinear term, is defined for the
two-dimensional Navier-Stokes equations. Numerical tests prove its
accuracy.
