Continuity
Abstract
Chapter 5 includes a first discussion of continuous functions. It starts with the definition of continuous functions in metric spaces and its discussion. Examples of a construction of different discontinuous functions are given. The limit concept for a function is defined and it is related to continuity. A special attention is giving to discontinuity points of real-valued functions of real variable. Continuous functions on compact and connected metric spaces are studied. Oscillation of a function is defined and related to continuity. The chapter ends with discussion of continuity for functions with values in finite dimensional Euclidean spaces.
