Abstract
A new Tau method is presented for the two dimensional Poisson equation Comparison
of the results for the test problem u(x,y)=sin(4πx)sin(4πy) with those computed by Haidvogel and
Zang, using the matrix diagonalization method, and Dang-Vu and Delcarte, using the Chebyshev
collocation method, indicates that our method would be more accurate.
