The paper shows that no origin-symmetric convex polyhedron in R^3 is the intersection body of a star body. It is shown also that every origin-symmetric convex body in R^d, for d = 3 and 4, can be seen as the intersection body of a star-shaped set whose radial function satisfies conditions related to suitable non-integer Sobolev classes.

Abstract

The paper shows that no origin-symmetric convex polyhedron in R^3 is the intersection body of a star body. It is shown also that every origin-symmetric convex body in R^d, for d = 3 and 4, can be seen as the intersection body of a star-shaped set whose radial function satisfies conditions related to suitable non-integer Sobolev classes.
