Pseudospectral and Galerkin Methods

1998
Wave equations have been successfully discretized using all of the standard families of algorithms: finite difference, finite element, and spectral. Nevertheless, this volume will review only Chebyshev and Fourier spectral methods.

Pseudospectral methods for Nagumo equation

International Journal for Numerical Methods in Biomedical Engineering, 2011
Summary: We present two pseudospectral methods based on Fourier series and rational Chebyshev functions for solving the Nagumo equation. In each of the two presented methods the problem is reduced to a system of ordinary differential equations that is solved by the leapfrog difference scheme and the fourth-order Runge-Kutta method, respectively.

A Hermite‐Lobatto Pseudospectral Method for Optimal Control

Asian Journal of Control, 2014
AbstractA pseudospectral (PS) method based on Hermite interpolation and collocation at the Legendre‐Gauss‐Lobatto (LGL) points is presented for direct trajectory optimization and costate estimation of optimal control problems. A major characteristic of this method is that the state is approximated by the Hermite interpolation instead of the commonly ...

Pseudospectral methods for pricing options

Quantitative Finance, 2009
Models with two or more risk sources have been widely applied in option pricing in order to capture volatility smiles and skews. However, the computational cost of implementing these models can be large—especially for American-style options. This paper illustrates how numerical techniques called ‘pseudospectral’ methods can be used to solve the partial

A generalization of the Fourier pseudospectral method

Geophysics, 2010
Abstract The Fourier pseudospectral (PS) method is generalized to the case of derivatives of nonnatural order (fractional derivatives) and irrational powers of the differential operators. The generalization is straightforward because the calculation of the spatial derivatives with the fast Fourier transform is performed in the ...
