On the convergence of a rule by Monegato for the numerical evaluation of Cauchy principal value integrals [PDF]

, 1988
: In this paper the authors examine the convergence of an interpolatory type quadrature rule proposed by G. Monegato for the evaluation of Cauchy principal value integrals. A convergence theorem is given for a large class of functions and some estimates

Efficient Polarization‐Entangled Photon‐Pair Generation by a Fiber‐In‐Line van der Waals Material

Advanced Science, EarlyView.
Telecom‐wavelength polarization‐entangled photon pairs are generated in a van der Waals‐material‐integrated all‐fiber device via spontaneous parametric down‐conversion. The demonstrated fiberized quantum light source bridges emerging 2D nonlinear materials and practical quantum photonic systems, opening new opportunities for scalable fiber‐based ...

Investigation of the solution of a boundary value problem with variable coefficients whose principal part is the Cauchy–Riemann equation

Қарағанды университетінің хабаршысы. Математика сериясы
This study is devoted to obtaining an analytical expression for the solution of a non-local boundary value problem for a linear inhomogeneous differential equation with variable coefficients, which principle part is the Cauchy–Riemann equation.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

On the convergence of spline product quadratures for Cauchy principal value integrals [PDF]

, 1991
In a recent paper (this journal (1990)), the authors proposed product integration formulas, for the numerical evaluation of the Cauchy principal value integral f1−1u(x) f;(x)/(x−λ) dx, based on cubic spline interpolation of f;, and obtained convergence ...

The Trapezoidal Rule for Computing Cauchy Principal Value Integral on Circle [PDF]

Mathematical Problems in Engineering, 2015
The composite trapezoidal rule for the computation of Cauchy principal value integral with the singular kernelcot((x-s)/2)is discussed. Our study is based on the investigation of the pointwise superconvergence phenomenon; that is, when the singular point coincides with some a priori known point, the convergence rate of the trapezoidal rule is higher ...

Error Expansion of Classical Trapezoidal Rule for Computing Cauchy Principal Value Integral [PDF]

, 2013
The composite classical trapezoidal rule for the computation of Cauchy principal value integral with the singular kernel 1/(x-s) is discussed. Based on the investigation of the superconvergence phenomenon, i.e., when the singular point coincides with ...
