The Steiner Subratio in Banach Spaces
L. Burusheva Lomonosov Moscow State University
Abstract:
For every $n=2,3,\dots$, the minimum of the Steiner subratio is found for $n$-point sets in Banach spaces, and an example of a Banach space is constructed for which this minimum is attained. An example of a Banach space for which the minimum possible Steiner subratio equals $1/2$ is also constructed.
Keywords:
Banach space, shortest network, minimal filling, Steiner subratio.
