摘要
A triangular spectral element method is proposed and analyzed for the Laplacian eigenvalue problem. The method is based on the Galerkin approximation with generalized Koornwinder polynomials. We detailedly describe the approximation scheme and implementation for solving the Laplacian eigenvalue problem. Numerical experiments also indicate that the triangular spectral element method for solving the eigenvalue problems on convex domain has the "spectral" accuracy, that is, exponential convergence rate.
