On Minimal Tilings with Convex Cells Each Containing a Unit Ball

چکیده
We investigate the following problem that one can regard as a very close relative of the densest sphere packing problem. If the Euclidean 3-space is partitioned into convex cells each containing a unit ball, how should the shapes of the cells be designed to minimize the average edge curvature of the cells? In particular, we prove that the average edge curvature in question is always at least 13:8564 : : :.

Gyrovector Spaces on the Open Convex Cone of Positive Definite Matrices
In this article we review an algebraic definition of the gyrogroup and a simplified version of the gyrovector space with two fundamental examples on the open ball of finite-dimensional Euclidean spaces, which are the Einstein and M"{o}bius gyrovector spaces. We introduce the structure of gyrovector space and the gyroline on the open convex cone of positive definite matrices and explore its...

We raise and investigate the following problem which one can regard as a very close relative of the densest sphere packing problem. If the Euclidean 3space is partitioned into convex cells each containing a unit ball, how should the shapes of the cells be designed to minimize the average surface area of the cells? In particular, we prove that the average surface area in question is always at le...
متن کاملSufficient enlargements of minimal volume for finite dimensional normed linear spaces
Let BY denote the unit ball of a normed linear space Y . A symmetric, bounded, closed, convex set A in a finite dimensional normed linear space X is called a sufficient enlargement for X if, for an arbitrary isometric embedding of X into a Banach space Y , there exists a linear projection P : Y → X such that P (BY ) ⊂ A. The main results of the paper: (1) Each minimal-volume sufficient enlargem...
متن کاملConvex Bodies of Minimal Volume, Surface Area and Mean Width with Respect to Thin Shells
Given r > 1, we consider the minimal volume, minimal surface area and minimal mean width of convex bodies in E that contain a unit ball, and the extreme points are of distance at least r from the centre of the unit ball; more precisely, we investigate the difference of these minimums and of the volume, surface area and mean width, respectively, of the unit ball. As r tends to one, we describe t...
متن کاملThe Dodecahedral Conjecture
A packing of congruent balls of unit radius in three-dimensional Euclidean space is determined by and is identified with the set Λ of centers of the balls. A packing Λ determines a region called the Voronoi cell around each ball. The Voronoi cell Ω(Λ, v) around a ball at v ∈ Λ consists of points of space that are closer to v than to any other w ∈ Λ. The Voronoi cell is a convex polyhedron conta...
