Generalizations of Metric SpacesSome immediate generalizations of the notion of metric, for example, ., ., ., were defined in Chap.?.. Here we give some generalizations in the direction of Topology, Probability, Algebra, etc.

Metrics on Normed StructuresIn this chapter we consider a special class of metrics defined on some ., as the norm of the difference between two given elements. This structure can be a group (with a .), a vector space (with a . or, simply, a .), a vector lattice (with a .), a field (with a .), etc.

Distances in Geometry . arose as the field of knowledge dealing with spatial relationships. It was one of the two fields of pre-modern Mathematics, the other being the study of numbers.

Distances on Surfaces and KnotsA . is a real two-dimensional . . ., i.e., a ., each point of which has a neighborhood which is homeomorphic to a plane ., or a closed half-plane (cf. Chap.?.).
