Refinement of Bezdek's conjecture for Larman points
Refinement of Bezdek's conjecture for Larman points
Let be a convex body with , and let . For every hyperplane passing through , suppose the section has an -plane of symmetry; then is a Larman point of . If, moreover, every such section has an -plane of symmetry containing , then is a revolution point of . Refinement of Bezdek's conjecture. Suppose that is a Larman point of which is not a revolution point of . Then either is an ellipsoid or is a body of revolution. This refinement concerns the global shape forced by the distinction between Larman and revolution points; the supplied source gives no resolution status.
