Abstract
In this article we study the properties of the hyperinterpolation opera-
tor on the unit disk D in R2
. We show how the hyperinterpolation can be
used in connection with the Kumar-Sloan method to approximate the so-
lution of a nonlinear Poisson equation on the unit disk (discrete Galerkin
method). A bound for the norm of the hyperinterpolation operator in the
