The purpose of this paper is to determine conditions under which equicontinuity of the family of iterates {f$^{n}$ } of a continuous function that maps the circle S$^{1}$ into itself does occur. We shall see that equicontinuity of the family of iterates {f$^{n}$ } occurs only under special cases. Actually, we will show that this happens only for rotations when degree of the function is 1, and for involutions when degree of the function is -1.

In study of the dynamics of a map f from a topological space X to itself, a central role is played by the various recursive properties of the points of X. One such property is periodicity. A weaker property is that of being nonwandering. Intermediate recursive properties include almost periodicity and recurrence.

In this paper, we study the inclusion realtion between recursive sets. And we prove that if $\overline{R(f)}{\backslash}R(f)$ is not empty, then it is infinite, and we characterize the necessary and sufficent condition for which $\overline{R(f)}{\backslash}R(f)$ is countable.

The purpose of this paper is to verify the appropriation of power electronics circuit by applying the most powerful and widely used simulator PSPICE and SIMULINK for adapted variable control technics. Power electronics librarys modeled and adapted to circuit. It is proved that simulation and excute are almost same.

Let I be the interval, $S^1$ the circle and let X be a compact metric space. And let $C^{circ}(X,\;X)$ denote the set of continuous maps from X into itself. For any f$f\in\;C\circ(X,\;X),\;let\;P(f),\;R(f),\;\Gamma(f),\;\Lambda(f)\;and\;\Omega(f)$ denote the collection of the periodic points, recurrent points, ${\gamma}-limit{\;}points,{\;}{\omega}-limit$ points and nonwandering points, respectively.(omitted)
