In this paper we characterize rational Szegő quadrature formulas associated with Chebyshev weight functions, by giving explicit expressions for the corresponding para-orthogonal rational functions and ...
Chebyshev polynomials, a central class of orthogonal polynomials, have long been pivotal in numerical analysis, approximation theory and the solution of differential equations. Their inherent ...
S. Li in [Studia Sci. Math. Hungar. 29 (1994) 71–83] proposed a Kronrod type extension to the well-known Turán formula. He showed that such an extension exists for any weight function. For the ...
