Book 1992oduce the students (and also the readers of the book) to some of the main methods of this theory. One can select two principal aspects of modern theory of structural stability (of course there are some conventions attached to this state- ment). The first one, let us call it the "geometric" aspect, d

By the Existence and Uniqueness Theorem there exists a number . > 0 such that there is a unique solution of system (1.1) defined on (-., .) and having the following property: The graph of the map is called the integral curve of this solution.
