Fast and Stable Harmonic Approximation from Ill-distributed Data using Moving Least Squares

Ralf Hielscher, Tim Pöschl, Erik Wünsche

We consider harmonic approximation on the torus $T^{d}$ , the sphere $S^{d}$ , and the rotation group $SO (3)$ . While several global approaches are available f…

An Optimal Ansatz Space for Moving Least Squares Approximation on Spheres

Ralf Hielscher, Tim Pöschl

We revisit the moving least squares (MLS) approximation scheme on the sphere $S^{d - 1} \subset R^{d}$ , where $d > 1$ . It is well known that using the spherical harmonics…
