Internality of Two-Measure-Based Generalized Gauss Quadrature Rules for Modified Chebyshev Measures II

open access: yesMathematics
Gaussian quadrature rules are commonly used to approximate integrals with respect to a non-negative measure dσ^. It is important to be able to estimate the quadrature error in the Gaussian rule used.

Variational Integrators in Holonomic Mechanics

open access: yesMathematics, 2020
Variational integrators for dynamic systems with holonomic constraints are proposed based on Hamilton’s principle. The variational principle is discretized by approximating the generalized coordinates and Lagrange multipliers by Lagrange polynomials, by ...

On the Remainder in Quadrature Rules [PDF]

open access: yesMathematics of Computation, 1971
An expression is obtained for the remainder in quadrature rules applied to functions whose Hubert transforms exist. The estimation of the remainder is illustrated by means of a particular example.

Upper Bounds for the Remainder Term in Boole’s Quadrature Rule and Applications to Numerical Analysis

open access: yesMathematics
In the current study, we compute some upper bounds for the remainder term of Boole’s quadrature rule involving convex mappings. First, we build a new identity for first-order differentiable mapping, an auxiliary result to establish our required estimates.

On the computation of Gaussian quadrature rules for Chebyshev sets of linearly independent functions [PDF]

open access: yes, 2017
We consider the computation of quadrature rules that are exact for a Chebyshev set of linearly independent functions on an interval $[a,b]$. A general theory of Chebyshev sets guarantees the existence of rules with a Gaussian property, in the sense that $

Onp-generator fully symmetric quadrature rules

open access: yesNumerische Mathematik, 1978
We consider fully symmetric quadrature rules for fully symmetricn-dimensional integration regions. When the region is a product region it is well known that product Gaussian rules exist. These obtain an approximation of polynomial degree 4p+1 based on (2p+1) n function values arranged on a rectangular grid.

Comprehensive Interpretation of a Three-Point Gauss Quadrature with Variable Sampling Points and Its Application to Integration for Discrete Data

open access: yesJournal of Applied Mathematics, 2013
This study examined the characteristics of a variable three-point Gauss quadrature using a variable set of weighting factors and corresponding optimal sampling points. The major findings were as follows.
