On Packings of Congruent Balls in the Unit Ball

1987
Let (X, ) be an infinite-dimensional real or complex inner product space. If I ≠O, r ∈ IR+: = (0,∞), uj ∈ X (for all j ∈ I), uj ≠ uk for j ≠ k, then the family (Br(uj): j ∈I) of open r-balls with centers uj is said to be packable ...

On Covering the Unit Ball in Normed Spaces

Canadian Mathematical Bulletin, 1971
By compactness, the unit ball Bn in Rn has a finite covering by translates of rBn, for any r > 0. The main theorem of this note shows that a weaker covering property does not hold in any infinite-dimensional normed space.

Vertices, Edges and Facets of the Unit Ball

Journal of Convex Analysis, 2019
It has been recently proved that every real Banach space can be endowed with an equivalent norm in such a way that the new unit sphere contains a convex subset with non-empty interior relative to the unit sphere. In fact, under good conditions like separability or being weakly compactly generated, this renorming can be accomplished to have a dense ...

On the density of unit balls touching a unit cylinder

Archiv der Mathematik, 1995
We give reasonably good upper bounds for the density of unit balls touching an infinite unit cylinder without overlapping each other in the 4-, 6- and 8-dimensional Euclidean spaces.
