Modified Busemann-Petty problem on sections of convex bodies

Functional Analysis 2007-05-23 v1

Abstract

The Busemann-Petty problem asks whether origin-symmetric convex bodies in Rn\mathbb{R}^n with smaller central hyperplane sections necessarily have smaller nn-dimensional volume. It is known that the answer is affirmative if n4n\le 4 and negative if n5n\ge 5. In this article we modify the assumptions of the original Busemann-Petty problem to guarantee the affirmative answer in all dimensions.
