Wavelet Galerkin method for fractional elliptic differential equations [PDF]

, 2014
Under the guidance of the general theory developed for classical partial differential equations (PDEs), we investigate the Riesz bases of wavelets in the spaces where fractional PDEs usually work, and their applications in numerically solving fractional ...

Wavelet-based density estimation for noise reduction in plasma simulations using particles [PDF]

, 2009
For given computational resources, the accuracy of plasma simulations using particles is mainly held back by the noise due to limited statistical sampling in the reconstruction of the particle distribution function.

A wavelet based numerical method for nonlinear partial differential equations

, 2003
The purpose of this paper is to present a wavelet–Galerkin scheme for solving nonlinear elliptic partial differential equations. We select as trial spaces a nested sequence of spaces from an appropriate biorthogonal multiscale analysis. This gives rise to a nonlinear discretized system.

Wavelet Methods in the Relativistic Three-Body Problem

, 2005
In this paper we discuss the use of wavelet bases to solve the relativistic three-body problem. Wavelet bases can be used to transform momentum-space scattering integral equations into an approximate system of linear equations with a sparse matrix.

Interval Wavelet Numerical Method on Fokker-Planck Equations for Nonlinear Random System [PDF]

Advances in Mathematical Physics, 2013
The Fokker-Planck-Kolmogorov (FPK) equation governs the probability density function (p.d.f.) of the dynamic response of a particular class of linear or nonlinear system to random excitation. An interval wavelet numerical method (IWNM) for nonlinear random systems is proposed using interval Shannon-Gabor wavelet interpolation operator.
