This is Python code that solves the nonlinear QG equations for PV anomalies on a doubly-periodic domain. It consists of two parts: a fully-dealiased pseudo-spectral code that steps forward the PV ...

Fourier spectral methods of Galerkin and collocation type for quasilinear pseudo-parabolic equations are presented. Convergence with spectral accuracy is proved for both Galerkin and collocation ...

The emphasis of this paper is to propose a method based on Legendre pseudo spectral method to solve the optimal landing path planning problem for navigable aircraft. By establishing the mathematical ...

We improved our previous numerical code based on pseudo-spectral methods in order to allow for possible discontinuities in the solution. Our algorithm based on a multidomain decomposition of the ...
