Chebyshev Polynomials in the Spectral tau Method and Applications to EigenvalueProblems

摘要

Chebyshev Spectral methods have received much attention recently as a techniquefor the rapid solution of ordinary differential equations. This technique also works well for solving linear eigenvalue problems. Specific detail is given to the properties and algebra of chebyshev polynomials; the use of chebyshev polynomials in spectral methods; and the recurrence relationships that are developed. These formula and equations are then applied to several examples which are worked out in detail. The appendix contains an example FORTRAN program used in solving an eigenvalue problem.
