Optimal Lebesgue constants for least squares polynomial approximation on the (hyper)sphere

Woula Themistoclakis, Marc Van Barel

We investigate the uniform approximation provided by least squares polynomials on the unit Euclidean sphere $S^{q}$ in $R^{q + 1}$ , with $q \geq 2$ . Like any other poly…

Uniform approximation on the sphere by least squares polynomials

Woula Themistoclakis, Marc Van Barel

The paper concerns the uniform polynomial approximation of a function $f$ , continuous on the unit Euclidean sphere of $R^{3}$ and known only at a finite number of points th…
