✦ Synopsis

We show that a standard spectral collocation scheme can be stabilized by adding extra trial/test functions with local support (bubbles). Applications are given to a scalar advection-diffusion problem and to the Stokes problem.

P. Fischer and J. Mullen [3] have recently proposed a stabilization technique for the solution of the unsteady Navier-Stokes equations with the spectral element method. It is based on interpolations in physical space: Given the values of a function u on a Gauss-Lobatto-Legendre (GLL) mesh with (N +
