Introduction To Topology (I).

      Аннотация: Topology is one of four major areas of abstract mathematics: algebra (equations), analysis (limits), foundations (set theory and logic), and topology. Broadly speaking, topology is the study of space and continuity. Since topology includes the study of continuous deformations of a space, it is often popularly called rubber sheet geometry. Vector spaces Rn are spaces, but a space can be a finite set of points or an infinite dimensional space of functions.
