Given a complete metric space X and a compact set C⊂X , the famous Steiner (or minimal connection) problem is that of finding a set S of minimum length (one-dimensional Hausdorff measure ℋ¹) ) among the class of sets St(C):={S⊂X:S∪C isconnected}. In this paper we provide conditions on existence of minimizers and study topological regularity results for solutions of this problem. We also study the relationships between several similar variants of the Steiner problem. At last, we provide some applications to locally minimal sets.

Abstract
Given a complete metric space X and a compact set C⊂X , the famous Steiner (or minimal connection) problem is that of finding a set S of minimum length (one-dimensional Hausdorff measure ℋ¹) ) among the class of sets St(C):={S⊂X:S∪C isconnected}. In this paper we provide conditions on existence of minimizers and study topological regularity results for solutions of this problem. We also study the relationships between several similar variants of the Steiner problem. At last, we provide some applications to locally minimal sets.File in questo prodotto:
