Stone-Weierstrass theorem for homogeneous polynomials and its role in convex geometry

Bernardo González Merino, Rafael Villa

We give a uniform approximation of the characteristic function of the boundary of a centrally symmetric n-dimensional compact and convex set by homogeneous polynomials of even degr…

Best approximation of functions by log-polynomials

David Alonso-Gutiérrez, Bernardo González Merino, Rafael Villa

Lasserre [La] proved that for every compact set $K \subset R^{n}$ and every even number $d$ there exists a unique homogeneous polynomial $g_{0}$ of degree $d$ with $K\subset G_1(…
