Well-Conditioned Spectral Collocation Methods for Problems in Unbounded Domains
Authors:Dongqin Gu  Chao Zhang & Zhongqing Wang
Abstract:Based on the generalized Laguerre and Hermite functions, we construct two types of Birkhoff-type interpolation basis functions. The explicit expressions are derived, and fast and stable algorithms are provided for computing these basis functions. As applications, some well-conditioned collocation methods are proposed for solving various second-order differential equations in unbounded domains. Numerical experiments illustrate that our collocation methods are more efficient than the standard Laguerre/Hermite collocation approaches.
Keywords:Spectral collocation methods  generalized Laguerre and Hermite functions  Birkhoff interpolation  fast and stable algorithms
