摘要：
We introduce polyhedral cones associated with m-hemimetrics on n points, and, in particular, with m-hemimetrics coming from partitions of an n-set into m + 1 blocks. We compute generators and facets of the cones for small values of m, n and study their skeleton graphs. (c) 2004 Elsevier B.V. All rights reserved.
