On Non-Oscillating Integrals for Computing Inhomogeneous Airy Functions [PDF]

open access: yes, 2000
Integral representations are considered of solutions of the inhomogeneous Airy differential equation $w''-z w=\pm1/\pi$. The solutions of these equations are also known as Scorer functions.

An Innovative Approach to Nonlinear Fractional Shock Wave Equations Using Two Numerical Methods

open access: yesMathematics, 2023
In this research, we propose a combined approach to solving nonlinear fractional shock wave equations using an Elzaki transform, the homotopy perturbation method, and the Adomian decomposition method. The nonlinear fractional shock wave equation is first

A method for the numerical integration of ordinary differential equations [PDF]

open access: yesMathematics of Computation, 1958
where y(x) denotes the solution of the differential equation. The idea is to use a quadrature formula to estimate the integral of (1). This requires knowledge of the integrand at specified arguments xi in (x0, xo + h)-hence we require the values of y(x) at these arguments.

On the Stability of Numerical Methods for Nonlinear Volterra Integral Equations

open access: yesDiscrete Dynamics in Nature and Society, 2010
Here we investigate the behavior of the analytical and numerical solution of a nonlinear second kind Volterra integral equation where the linear part of the kernel has a constant sign and we provide conditions for the boundedness or decay of solutions ...

THE NUMERICAL METHODS FOR SOLVING NONLINEAR INTEGRAL EQUATIONS

open access: yesIJRDO -JOURNAL OF MATHEMATICS, 2023
Volterra integral equations are a special type of integrative equations; they are divided into two categories referred to as the first and second type. This thesis will deal with the second type which has wide range of the applications in physics and engineering problems.

Gr\"obner Bases and Generation of Difference Schemes for Partial Differential Equations [PDF]

open access: yes, 2006
In this paper we present an algorithmic approach to the generation of fully conservative difference schemes for linear partial differential equations. The approach is based on enlargement of the equations in their integral conservation law form by extra ...
