Interpolation method for solving Volterra integral equations with weakly singular kernel using an advanced barycentric Lagrange formula

open access: yesAin Shams Engineering Journal, 2022
We presented an interpolation method for solving weakly singular Volterra integral equations of the second kind (SVK2). The method based on the barycentric Lagrange interpolation.. For the chosen nodes of the two singular kernel variables, we created two

Vibration analysis of airfoil on hereditary deformable suspensions [PDF]

open access: yesE3S Web of Conferences, 2019
This paper describes the analyses of the nonlinear vibrations and dynamic stability of an airfoil on hereditary-deformable suspensions. The model is based on two-degree-of-freedom structure in geometrically nonlinear statements. It provides justification

A Numerical Study for the Dirichlet Problem of the Helmholtz Equation

open access: yesMathematics, 2021
In this paper, an effective numerical method for the Dirichlet problem connected with the Helmholtz equation is proposed. We choose a single-layer potential approach to obtain the boundary integral equation with the density function, and then we deal ...

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]

open access: yes, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

Fast solvers of weakly singular integral equations of the second kind

open access: yesMathematical Modelling and Analysis, 2018
We discuss the bounds of fast solving weakly singular Fredholm integral equations of the second kind with a possible diagonal singularity of the kernel and certain boundary singularities of the derivatives of the free term when the information about the ...
