Best polynomial approximation on the unit ball

Miguel Pinar, Yuan Xu

Let $E_{n} (f)_{μ}$ be the error of best approximation by polynomials of degree at most $n$ in the space $L^{2} (ϖ_{μ}, B^{d})$ , where $B^{d}$ is the unit ball in $\mathbb…

Three term relations for a class of bivariate orthogonal polynomials

Misael Marriaga, Teresa E. Pérez, Miguel A. Piñar

We study matrix three term relations for orthogonal polynomials in two variables constructed from orthogonal polynomials in one variable. Using the three term recurrence relation f…

Multivariate Orthogonal Polynomials and Modified Moment Functionals

Antonia M. Delgado, Lidia Fernández, Teresa E. Pérez +1

Multivariate orthogonal polynomials can be introduced by using a moment functional defined on the linear space of polynomials in several variables with real coefficients. We study…
