A Collocation Numerical Method for Highly Oscillatory Algebraic Singular Volterra Integral Equations

open access: yesFractal and Fractional
The highly oscillatory algebraic singular Volterra integral equations cannot be solved directly. A collocation numerical method is proposed to overcome the difficulty created by the highly oscillatory algebraic singular kernel.

A collocation spectral method for two-dimensional Sobolev equations

open access: yesBoundary Value Problems, 2018
This article mainly studies a collocation spectral method for two-dimensional (2D) Sobolev equations. To this end, a collocation spectral model based on the Chebyshev polynomials for the 2D Sobolev equations is first established. And then, the existence,

An Overrange Collocation Method

open access: yesComputer Modeling in Engineering & Sciences, 2011
In this paper, a new meshless method called the overrange collocation method (ORCM) is proposed. By introducing some collocation points, which are located at outside of domain of the analyzed body, unsatisfactory issue of the positivity conditions of boundary points in collocation methods can be avoided.

One-Point Spectrum Nordsieck Almost Collocation Methods

open access: yesInternational Journal of Circuits, Systems and Signal Processing, 2020
A family of multivalue collocation methods for the numerical solution of differen- tial problems is proposed. These methods are developed in order to be suitable for the solu- tion of stiff problems, since they are highly stable and do not suffer from order reduction, as they have uniform order of convergence in the whole integration interval.
