On the isometric conjecture of Banach

Let $V$ be a Banach space where for fixed $n$, $1<n<\dim(V)$, all of its $n$-dimensional subspaces are isometric. In 1932, Banach asked if under this hypothesis $V$ is necessarily a Hilbert space.

Dualities and endomorphisms of pseudo-cones

The Minkowski Measure of Asymmetry for Spherical Bodies of Constant Width

In this paper, we introduce the Minkowski measure of asymmetry for the spherical bodies of constant width. Then we prove that the spherical balls are the most symmetric bodies among all spherical

On Wendel’s equality for intersections of balls

We study the analogue of Wendel’s equality in random polytope models in which the hull of the random points is formed by intersections of congruent balls, called the spindle (or hyper-) convex hull.

Some extremal problems for polygons in the Euclidean plane

. The paper is devoted to some extremal problems, related to convex polygons in the Euclidean plane and their perimeters. We present a number of results that have simple formulations, but rather

Reflections of convex bodies and their sections

. The purpose of this paper is to study the reflections of a convex body. In particular, we are interested in orthogonal reflections of its sections that can be extended to reflections of the whole

A new duality on closed convex sets

In this paper we study a subclass of convex sets which are called closed pseudo-cones and introduce a new duality on this subclass. It turns out that the new duality characterizes closed pseudo-cones
