A new representation of generalized averaged Gauss quadrature rules [PDF]
, 2021 Gauss quadrature rules associated with a nonnegative measure with support on (part of) the real axis find many applications in Scientific Computing. It is important to be able to estimate the quadrature error when replacing an integral by an l-node Gauss

Error Estimates for Certain Cubature Formulae [PDF]
, 2017 We estimate the errors of selected cubature formulae constructed by the product of Gauss quadrature rules. The cases of multiple and (hyper-)surface integrals over n-dimensional cube, simplex, sphere and ball are considered.

Properties and numerical solutions of dispersion curves in general isotropic waveguides [PDF]
, 2013 In this paper, some properties of dispersion curves in general isotropic piecewise homogeneous waveguides are rigorously derived. These properties are leveraged in a numerical implementation capable of determining the dispersion curves of such waveguides

Generalized averaged gaussian formulas for certain weight functions [PDF]
, 2022 In this paper we analyze the generalized averaged Gaussian quadrature formulas and the simplest truncated variant for one of them for some weight functions on the interval [0, 1] considered by Milovanovic in [10].

Sparse Quadrature for High-Dimensional Integration with Gaussian Measure [PDF]
, 2017 In this work we analyze the dimension-independent convergence property of an abstract sparse quadrature scheme for numerical integration of functions of high-dimensional parameters with Gaussian measure. Under certain assumptions of the exactness and the
