| Abstract: | Fourier-Chebyshev pseudospeotral scheme with mixed generalized Boohner fltering technique is proposed for e two-dimensional unsteady vorticity equation.The generalized stability and convergence are proved strictly.The numerical results are presented.The theoretical analysis in this paper provides a framework for error estimations of such mixed approximation. |
