Abel's Integral Equation as a Convolution Transform [PDF]

open access: yesProceedings of the American Mathematical Society, 1956
the first equation to be treated and solved as an integral equation, has an extensive literature, dealing on the one hand with properties of the functions involved, and on the other hand with the solution, and conditions for solubility of the equation. In the first category one might cite, in the modern spirit, the memoirs of Hardy [1, pp.

On the approximation of Volterra integral equations with highly oscillatory Bessel kernels via Laplace transform and quadrature

open access: yesAlexandria Engineering Journal, 2019
The present work focuses on formulating a numerical scheme for approximation of Volterra integral equations with highly oscillatory Bessel kernels. The application of Laplace transform reduces integral equations into algebraic equations.

Integral transforms, convolution products, and first variations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We establish the various relationships that exist among the integral transform ℱα,βF, the convolution product (F∗G)α, and the first variation δF for a class of functionals defined on K[0, T], the space of complex‐valued continuous functions on [0, T] which vanish at zero.

open access: yesKorean Journal of Mathematics, 2012
Summary: We study various relationships that exist among generalized conditional integral transform, generalized conditional convolution and generalized first variation for a class of functionals defined on \(K[0, T]\), the space of complex-valued continuous functions on \([0, T]\) which vanish at zero.

On the Convolution Quadrature Rule for Integral Transforms with Oscillatory Bessel Kernels [PDF]

open access: yesSymmetry, 2018
Lubich’s convolution quadrature rule provides efficient approximations to integrals with special kernels. Particularly, when it is applied to computing highly oscillatory integrals, numerical tests show it does not suffer from fast oscillation. This paper is devoted to studying the convergence property of the convolution quadrature rule for highly ...
