Convex Optimization for Rendezvous and Proximity Operation via Birkhoff Pseudospectral Method
Aerospace, 2022 Rapid and accurate rendezvous and proximity operations for spacecraft are crucial to the success of most space missions. In this paper, a sequential convex programming method, combined with the first-order and second-order Birkhoff pseudospectral methods,

ROME: A Pseudo‐Spectral Algorithm for Time‐Dependent Shear Flows in Stratified Environments
Journal of Advances in Modeling Earth Systems, 2021 Parameterizations of small‐scale mixing are important in modeling the behavior of the World Ocean. These microstructure mixing processes do not exist in isolation, however, and larger‐scale processes can affect their fluxes, which is an important ...

Pseudospectral Method for the "Good" Boussinesq Equation [PDF]
Mathematics of Computation, 1991 The paper deals with the pseudospectral time-discrete method for the ''good'' Boussinesq equation. The difficulties in the study of the stability of the aliasing error in the nonlinear term are removed in a way which is roughly equivalent to the use of negative Sobolev norms. Numerical comparisons with finite difference schemes are also given.

Dynamical Analysis of Fractional Integro-Differential Equations
Mathematics, 2022 In this article, we solve fractional Integro differential equations (FIDEs) through a well-known technique known as the Chebyshev Pseudospectral method. In the Caputo manner, the fractional derivative is taken.

Strong convergence estimates for pseudospectral methods [PDF]
, 1992 summary:Strong convergence estimates for pseudospectral methods applied to ordinary boundary value problems are derived. The results are also used for a convergence analysis of the Schwarz algorithm (a special domain decomposition technique).

A Pseudospectral Method for Hammerstein Equations
Journal of Mathematical Analysis and Applications, 1996 The paper is concerned with the numerical solution of the Hammerstein integral equation \[ y(t) - \int^1_0k(t,s)g \bigl(s,y(s) \bigr)ds=f(t), \quad t\in[-1,1], \tag{1} \] with \(g\) nonlinear in \(y\). The proposed method is applied not to equation (1), but rather to an equivalent equation \(z(t) = g(t,y(t))\), where \(z\) is approximated by algebraic ...
