TY - JOUR A1 - Diethelm, Kai T1 - Interpolatory product quadratures for Cauchy principal value integrals with Freud weights T2 - Numerische Mathematik N2 - We prove convergence results and error estimates for interpolatory product quadrature formulas for Cauchy principal value integrals on the real line with Freud–type weight functions. The formulas are based on polynomial interpolation at the zeros of orthogonal polynomials associated with the weight function under consideration. As a by–product, we obtain new bounds for the derivative of the functions of the second kind for these weight functions.
