Stochastic boundary collocation and spectral methods for solving PDEs

Monte Carlo Methods and Applications, 2012
We develop a stochastic boundary method (SBM) which can be considered as a randomized version of the method of fundamental solutions (MFS). We suggest solving the large system of linear equations for the weights in the expansion over the fundamental solutions by a randomized SVD method introduced by Sabelfeld and Mozartova (2011).

Least‐squares spectral collocation method for the Stokes equations

Numerical Methods for Partial Differential Equations, 2003
AbstractFirst‐order system least‐squares spectral collocation methods are presented for the Stokes equations by adopting the first‐order system and modifying the least‐squares functionals in 2. Then homogeneous Legendre and Chebyshev (continuous and discrete) functionals are shown to be elliptic and continuous with respect to appropriate product ...

Piecewise spectral collocation method for system of Volterra integral equations

Advances in Computational Mathematics, 2016
This paper describes a collocation method for the numerical solution of a system of linear Volterra integral equations of the form \[ {\mathbf y}(t) = {\mathbf g}(t) + \int_0^t {\mathbf K}(t,s) {\mathbf y}(s) \,ds. \] The interval \([0,T]\) is divided into subintervals of width \(\leq h\).

A Nonoverlapping Domain Decomposition Method for Legendre Spectral Collocation Problems

Journal of Scientific Computing, 2007
This paper deals with the Legendre spectral collocation method in a non-overlapping domain decomposition version to solve Poisson's equation in an \(L\)-shaped region. The collocation equations use Gauss-Legendre nodes instead of the more usual Gauss-Legendre-Lobatto points. The problem is decoupled into several independent steps.
