Bounds on Turán determinants
Let μ denote a symmetric probability measure on [−1, 1] and let (pn) be the corresponding orthogonal polynomials normalized such that pn(1) = 1. We prove that the normalized Turán determinant ∆n(x)/(1−x), where ∆n = pn−pn−1pn+1, is a Turán determinant of order n− 1 for orthogonal polynomials with respect to (1− x2)dμ(x). We use this to prove lower and upper bounds for the normalized Turán deter...
متن کاملMultivariate Christoffel functions and hyperinterpolation
We obtain upper bounds for Lebesgue constants (uniform norms) of hyperinterpolation operators via estimates for (the reciprocal of) Christoffel functions, with different measures on the disk and ball, and on the square and cube. As an application, we show that the Lebesgue constant of total-degree polynomial interpolation at the Morrow-Patterson minimal cubature points in the square has an O(de...
متن کاملPfaffians, Determinants, and Multivariable Christoffel–darboux Kernels
Abstract. We obtain expressions for the Christoffel–Darboux kernel of antisymmetric multivariable orthogonal polynomials as determinants and pfaffians. These kernels include correlation functions of orthogonal polynomial ensembles (with β = 2). In subsequent work, our results are applied in combinatorics (enumeration of marked shifted tableaux) and number theory (representation of integers as s...

متن کاملOn Christoffel Functions and Related Quantities for Compactly Supported Measures
Let be a compactly supported positive measure on the real line, with associated orthogonal polynomials fpng. Without any global restrictions such as regularity, we discuss convergence in measure for (i) ratio asymptotics for Christo¤el functions; (ii) the Nevai operators (aka the Nevai condition); (iii) universality limits in the bulk. We also establish convergence a.e. for su¢ cently sparse su...
