Nested quadrature rules for Cauchy principal value integrals [PDF]

open access: yesJournal of Computational and Applied Mathematics, 1989
Starting from ideas of \textit{G. Monegato} [Computing 29, 337-354 (1982; Zbl 0485.65017)] and \textit{P. Rabinowitz} [Math. Comput. 41, 63-78 (1983; Zbl 0545.65012)], the author builds new cubature formulae to numerically evaluate integrals of Cauchy type \(\int^{b}_{a}f(x)/(x-\lambda)dx\), \(-\infty

Asymptotic behaviour of fixed-order error constants of modified quadrature formulae for Cauchy principal value integrals [PDF]

open access: yesJournal of Inequalities and Applications, 2000
We consider quadrature formulae for Cauchy principal value integrals The quadrature formulae considered here are so-called modified formulae, which are obtained by first subtracting the singularity, and then applying some standard quadrature formula ...

A Class of Quadrature Rules for Complex Cauchy Principal Value Integrals [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2023
This article is fully devoted to the numerical approximation of Cauchy-type integrals in the complex plane. A class of degree eight quadrature rules is formulated from a family of Gauss-type two-point rules based on the method of extrapolation. The basic

TWO LOW-ORDER METHODS FOR THE NUMERICAL EVALUATION OF CAUCHY PRINCIPAL VSlLUE INTEGRALS OF OSCILLATORY KIND [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2000
In this paper, we develop two piecewise polynomial methods for the numerical evaluation of Cauchy Principal Value integrals of oscillatory kind. The two piecewisepolynomial quadratures are compact, easy to implement, and are numerically stable.

The Hilbert transform [PDF]

open access: yesSurveys in Mathematics and its Applications, 2021
The Hilbert transform is essentially the only singular operator in one dimension. This undoubtedly make it one of the most important linear operator in harmonic analysis.

OPERATOR METHOD IN THE PROBLEM OF THE H-POLARIZED WAVE DIFFRACTION BY TWO SEMI-INFINITE GRATINGS PLACED IN THE SAME PLANE [PDF]

open access: yesRadio Physics and Radio Astronomy, 2021
Purpose: Problem of the H-polarized plane wave diffraction by the structure, which consists of two semi-infinite strip gratings, is considered. The gratings are placed in the same plane. The gap between the gratings is arbitrary. The purpose of the paper
