Vector Fields,Scalar fields (see 1.1) and vector fields (see 1.2 and 1.5) are mathematical models derivedfrom laws of nature, among which we cite the following examples:

If the physical system remains in a neighbourhood of the equilibrium point x. when the evolution starts in a neighbourhood of x., then the point x. is said to be stable; if not, it is said to be unstable.

From these we shall present only the basic ideas and examples, noting however that the general theory requires supplementary knowledge of functional analysis, topology and dynamical systems.
