Quadrature formulas on combinatorial graphs

International Journal of Wavelets, Multiresolution and Information Processing
The goal of the paper is to establish quadrature formulas on combinatorial graphs. Three types of quadrature formulas are developed. Quadrature formulas of the first type are obtained through interpolation by variational splines. This set of formulas is exact on spaces of variational splines on graphs.

A quadrature formula for the Hankel transform

Numerical Algorithms, 1995
Quadrature formulas for the integral transform to be composed by two Hankel transforms and for the closely related Hankel transform are presented, the error produced by this algorithm for a class of piecewise continuous functions is estimated and some numerical examples are listed.

On Quadrature Formulae Near Gaussian Quadrature

1992
In this paper, for product integration on the finite interval [a, b], we consider the class of n-point quadrature formulae Q n of at least algebraic degree 2n – 3. We study a new approach for their characterization using the simple fact that such a quadrature formula is uniquely determined by one node y and its associated weight b. For a given node y ∈
