On Packings of Congruent Balls in the Unit Ball
1987Let (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, 1971By 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.

On the density of unit balls touching a unit cylinder
Archiv der Mathematik, 1995We 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.
