Notions of denseness
The notion of a completely saturated packing [Fejes Toth, Kuperberg
and Kuperberg, Highly saturated packings and reduced coverings,
Monats. Math. 125 (1998) 127-145] is a sharper version of maximum
density, and the analogous notion of a completely reduced covering is
a sharper version of minimum density. We define two related notions:
uniformly recurrent and weakly recurrent dense packings, and
diffusively dominant packings. Every compact domain in Euclidean space
has a uniformly recurrent dense packing. If the domain self-nests,
such a packing is limit-equivalent to a completely saturated
one. Diffusive dominance is yet sharper than complete saturation and
leads to a better understanding of n-saturation.
