Given a planar compact set Ω where a weakly admissible mesh (WAM) is known, we compute WAMs and the corresponding discrete extremal sets for polynomial interpolation on solid (even truncated) cones with base Ω (with pyramids as a special case), and on solids corresponding to the rotation of Ω around an external coplanar axis by a given angle.

Abstract
Given a planar compact set Ω where a weakly admissible mesh (WAM) is known, we compute WAMs and the corresponding discrete extremal sets for polynomial interpolation on solid (even truncated) cones with base Ω (with pyramids as a special case), and on solids corresponding to the rotation of Ω around an external coplanar axis by a given angle.File in questo prodotto:
