A Note on Some Approximation Kernels on the Sphere [PDF]
arXiv, 2017 We produce precise estimates for the Kogbetliantz kernel for the approximation of functions on the sphere. Furthermore, we propose and study a new approximation kernel, which has slightly better properties.

A Review of Prolate Spheroidal Wave Functions from the Perspective of Spectral Methods
, 2017This paper is devoted to a review of the prolate spheroidal wave functions (PSWFs) and their variants from the viewpoint of spectral/spectral-element approximations using such functions as basis functions.

Extremal Polynomials on Discrete Sets
, 1999We study asymptotics for orthogonal polynomials and other extremal polynomials on infinite discrete sets, typical examples being the Meixner polynomials and the Charlier polynomials.

Strong Truncated Matrix Moment Problem of Hamburger
Sarajevo Journal of MathematicsIn this paper we consider the strong truncated matrix moment problem on the real line. We describe all the solutions of the problem in the form of a Nevanlinna type formula. We use M. G.

Generating Function: Multiple Orthogonal Polynomials
, 2016In this paper we present a general methodology to obtain a generating function for some multiple orthogonal polynomials of type I with regular indices. In particular, we obtain an explicit generating functions Px(t) := ∑∞ n=0Q2n(x)t n and Ix(t) := ∑∞ n ...
