University of Bialystok

Summary.

The concept of the minimal distance between two sets in a Euclidean space is introduced and some useful lemmas are proved.

This work has been partially supported by the European Community TYPES grant IST-1999-29001 and CALCULEMUS grant HPRN-CT-2000-00102. The work was completed while the author visited Shinhsu University (Nagano).
