A Perturbed Milne’s Quadrature Rule for n-Times Differentiable Functions with Lp-Error Estimates

open access: yesAxioms, 2023
In this work, a perturbed Milne’s quadrature rule for n-times differentiable functions with Lp-error estimates is derived. One of the most important advantages of our result is that it is verified for p-variation and Lipschitz functions. Several error estimates involving Lp-bounds are proven.

High performance quadrature rules: how numerical integration affects a popular model of product differentiation [PDF]

open access: yesSSRN Electronic Journal, 2011
Efficient, accurate, multi-dimensional, numerical integration has become an important tool for approximating the integrals which arise in modern economic models built on unobserved heterogeneity, incomplete information, and uncertainty. This paper demonstrates that polynomialbased rules out-perform number-theoretic quadrature (Monte Carlo) rules both ...

Numerical Solution of Fractional Order Integro-Differential Equations via Müntz Orthogonal Functions

open access: yesJournal of Mathematics, 2023
In this paper, we derive a spectral collocation method for solving fractional-order integro-differential equations by using a kind of Müntz orthogonal functions that are defined on 0,1 and have simple and real roots in this interval.
