CONCEPTS OF METRIC SPACE

Описание: the subject of real number has two types of properties the first type consists of the algebraic which days with the addition multiplication etc the second type consists of properties having to do with the notation of distance between two numbers and with the concept of limit the second types of properties are call topological are metric in this chapter we shall study this properties in general space in which the notion of distance is define definition of metric space is defined as let capital X be an an impetus it then a mapping d:X~R is said to be metric iff it satisfy metric four conditions.
