We investigate the use of orthonormal polynomials over the unit disk 𝔹2 in ℝ2 and the unit ball 𝔹3 in ℝ3. An efficient evaluation of an orthonormal polynomial basis is given, and it is used in… (More)

In this article we study the properties of the hyperinterpolation operator on the unit disk D in R. We show how the hyperinterpolation can be used in connection with the Kumar-Sloan method to… (More)
