Matricial Gaussian quadrature rules: singular case
Let $L$ be a linear operator on univariate polynomials of bounded degree taking values in real symmetric matrices, whose moment matrix is positive semidefinite. Assume that $L$ admits a positive matrix-valued representing measure $μ$. Any finitely atomic representing measure with the smallest sum of the ranks of the matricial masses is called minimal ...

Gauss quadrature rules for refinable weight functions
, 2000 A two-parameter class of refinable functions is considered and Gaussian quadrature rules having these functions as weight functions. A discretization method is described for generating the recursion coefficients of the required orthogonal polynomials ...

Symmetric quadrature rules on a triangle
, 2003 We present a class of quadrature rules on triangles in R2 which, somewhat similar to Gaussian rules on intervals in R1, have rapid convergence, positive weights, and symmetry.

On generalized Gaussian quadrature rules for singular and nearly singular integrals
, 2008 We construct and analyze generalized Gaussian quadrature rules for integrands with endpoint singularities or near endpoint singularities. The rules have quadrature points inside the interval of integration and the weights are all strictly positive.

Trigonometric Quadrature Fourier Features for Scalable Gaussian Process Regression
, 2023 Fourier feature approximations have been successfully applied in the literature for scalable Gaussian Process (GP) regression. In particular, Quadrature Fourier Features (QFF) derived from Gaussian quadrature rules have gained popularity in recent years ...

Gaussian Quadrature Rule using {\epsilon}-Quasiorthogonality
, 2018 We introduce a new type of quadrature, known as approximate Gaussian quadrature (AGQ) rules using {\epsilon}-quasiorthogonality, for the approximation of integrals of the form \int f(x)d \alpha(x). The measure {\alpha}(\cdot) can be arbitrary as long as it possesses finite moments {\mu}n for sufficiently large n.
