Review
"nice contribution to the study of Steiner trees and a useful reference to the researchers in mathematics and computer science." -- Mathematics Abstracts, 2002
Product Description
This book deals with the new class of one-dimensional variational problems - the problems with branching solutions. Instead of extreme curves (mappings of a segment to a manifold) we investigate extreme networks, which are mappings of graphs (one-dimensional cell complexes) to a manifold. Various applications of the approach are presented, such as several generalizations of the famous Steiner problem of finding the shortest network spanning given points of the plane.
