Subdividing a Convex Body by a System of Cones and Polytopes Inscribed in the Body

Abstract

The literature contains quite a few theorems on subdividing the volume of a convex body by a system of cones and on the possibility to circumscribe the body about a polytope of one type or another. See R. N. Karasev, “Topological methods in combinatorial geometry,” Russian Math. Surveys, 63, No. 6, 1031–1078 (2008) for a survey of similar results. In the following, we also prove theorems of this kind. As a limit case, we obtain well-known theorems on inscribed polytopes.
