Localized method of particular solutions using polynomial basis functions for solving two-dimensional nonlinear partial differential equations

open access: yesPartial Differential Equations in Applied Mathematics, 2021
The localized method is one of the popular approaches in solving large-scale problems in science and engineering. In this paper, we implement the localized method of particular solutions using polynomial basis functions for solving various nonlinear ...

Regular Families of Kernels for Nonlinear Approximation

open access: yes, 2019
This article studies sufficient conditions on families of approximating kernels which provide $N$--term approximation errors from an associated nonlinear approximation space which match the best known orders of $N$--term wavelet expansion.

Radial basis functions-finite differences collocation and a Unified Formulation for bending, vibration and buckling analysis of laminated plates, according to Murakami's zig-zag theory [PDF]

open access: yes, 2011
In this paper, we propose to use the Murakami's zig-zag theory for the static and vibration analysis of laminated plates, by local collocation with radial basis functions in a finite differences framework.

Determination of an Extremal in Two-Dimensional Variational Problems Based on the RBF Collocation Method

open access: yesEntropy, 2022
This paper introduces a direct method derived from the global radial basis function (RBF) interpolation over arbitrary collocation nodes occurring in variational problems involving functionals that depend on functions of a number of independent variables.

Error estimates for interpolation of rough data using the scattered shifts of a radial basis function

open access: yes, 2007
The error between appropriately smooth functions and their radial basis function interpolants, as the interpolation points fill out a bounded domain in R^d, is a well studied artifact. In all of these cases, the analysis takes place in a natural function
