Abstract

In this work we prove that if for a pair of convex bodies K1,K2RnK_1, K_2 \subset \mathbb{R}^n, n3n \geq 3, there exists a hyperplane HH and two distinct points p1p_1 and p2p_2 in RnH\mathbb{R}^n \setminus H such that for every (n2)(n-2)-plane MHM \subset H, there exists a reflection mapping the hypersection of K1K_1 defined by aff{p1,M}\mathrm{aff}\{p_1, M\} onto the hypersection of K2K_2 defined by aff{p2,M}\mathrm{aff}\{p_2, M\}, then there exists a reflection which maps K1K_1 onto K2K_2.
