Abstract

In this talk, an efficient spectral method will be proposed for solving singular problems and singularly perturbed problems. Based on the Log mapping to Laguerre, the new bases are capable of exponentially approximating one-point singular functions and some boundary layer functions. The related Log spectral methods are applied to some fundamental singular problems and singularly perturbed problems, respectively. The numerical experiments are demonstrated to verify the high-efficiency of the new method.
