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 ...

Explicit formulas for the Dunkl dihedral kernel and the (κ,a)-generalized Fourier kernel

Journal of Mathematical Analysis and Applications, 2018
In this paper, a new method is developed to obtain explicit and integral expressions for the kernel of the (k,a)-generalized Fourier transform for k=0. In the case of dihedral groups, this method is also applied to the Dunkl kernel as well as the Dunkl ...
