Abstract

Orthogonal polynomials are widely used in numerical analysis. For example, the zeros of orthogonal polynomials are used as nodes of Gaussian quadrature formulas for numerical approximation of integrals. In this talk, we will discuss recent applications of orthogonal polynomials in parallel numerical computation of initial value problems. We will also prove the Harris-Simanek conjecture on bivariate Lagrange interpolation, which is related to the numerical analysis of a double integral.
