spectral-Tau formulation; Stokes problem; pressure approximation; spurious modes; spectral convergence
A new spectral-Tau formulation for the Stokes problem is introduced and analyzed. The pressure approximation of the resulting system does not contain any spurious modes. Moreover, the scheme is easy to implement numerically. The spectral convergence of the scheme is proved and is affirmed by numerical results.
