Generalized Gaussian Quadratures for Integrals with Logarithmic Singularity

Abstract

A short account on Gaussian quadrature rules for integrals
with logarithmic singularity, as well as some new results for weighted Gaussian quadrature formulas with respect to generalized Gegenbauer weight $x\mapsto |x|^\gamma(1-x^2)^\alpha$,
$\alpha,\gamma>-1$, on $(-1,1)$, which are appropriated for functions with and without logarithmic singularities, are considered. Methods for constructing such kind of quadrature formulas and some numerical examples are included.
