In this paper we investigate different questions concerning
Mazur sets in normed spaces, which point out the close connections
between geometric functional analysis and discrete geometry.
Motivated by a result of
Chen and Lin, we study the relationship between Mazur disks and
weak* denting points of the dual unit ball. We prove
that the only Mazur sets of the spaces l1n are points
and closed balls. Finally, a new stability property for the
family of all sets which are intersections of closed balls is found. 相似文献

A non-empty set X of vertices of an acyclic digraph is called connected if the underlying undirected graph induced by X is connected and it is called convex if no two vertices of X are connected by a directed path in which some vertices are not in X. The set of convex sets (connected convex sets) of an acyclic digraph D is denoted by and its size by co(D) (cc(D)). Gutin et al. (2008) conjectured that the sum of the sizes of all convex sets (connected convex sets) in D equals Θ(n · co(D)) (Θ(n · cc(D))) where n is the order of D. In this paper we exhibit a family of connected acyclic digraphs with and . We also show that the number of connected convex sets of order k in any connected acyclic digraph of order n is at least n − k + 1. This is a strengthening of a theorem of Gutin and Yeo. 相似文献

We derive a new representation formula for lower-semicontinuous convex functions on separable normed spaces. As a consequence of this formula, we obtain a C
