چکیده
Abstract Three term relations for orthogonal polynomials in several variables associated to a moment linear functional obtained by Uvarov modification of given are studied. Existence is analyzed, stating conditions ensure it. The matrices the three explicitly terms satisfied original family. Two examples presented order show that results valid positive definite functionals and also some quasi which not definite.

A formula for the coefficients of orthogonal polynomials from the three-term recurrence relations
In this work, the coefficients of orthogonal polynomials are obtained in closed form. Our formula works for all classes of orthogonal polynomials whose recurrence relation can be put in the form Rn(x) = x Rn−1(x) − αn−2 Rn−2(x). We show that Chebyshev, Hermite and Laguerre polynomials are all members of the class of orthogonal polynomials with recurrence relations of this form. Our formula unif...
متن کاملMOPS: Multivariate orthogonal polynomials (symbolically)
In this paper we present a Maple library (MOPs) for computing Jack, Hermite, Laguerre, and Jacobi multivariate polynomials, as well as eigenvalue statistics for the Hermite, Laguerre, and Jacobi ensembles of Random Matrix theory. We also compute multivariate hypergeometric functions, and offer both symbolic and numerical evaluations for all these quantities. We prove that all algorithms are wel...
متن کاملRecurrence Formulas for Multivariate Orthogonal Polynomials
In this paper, necessary and sufficient conditions are given so that multivariate orthogonal polynomials can be generated by a recurrence formula. As a consequence, orthogonal polynomials of total degree n in d variables that have dim n¡( common zeros can now be constructed recursively. The result is important to the construction of Gaussian cubature formulas.
متن کاملOrthogonality Relations for Multivariate Krawtchouk Polynomials
The orthogonality relations of multivariate Krawtchouk polynomials are discussed. In case of two variables, the necessary and sufficient conditions of orthogonality is given by Grünbaum and Rahman in [SIGMA 6 (2010), 090, 12 pages]. In this study, a simple proof of the necessary and sufficient condition of orthogonality is given for a general case.
متن کاملMultivariate Orthogonal Polynomials and Operator Theory
The multivariate orthogonal polynomials are related to a family of commuting selfadjoint operators. The spectral theorem for these operators is used to prove that a polynomial sequence satisfying a vector-matrix form of the three-term relation is orthonormal with a determinate measure.
