Abstract

We consider the following differential equation in R n ,
$$x = f(t,x,u)$$
(1.1)
. The point
$$x = \left( {\mathop{ \vdots }\limits_{{{x^{n}}}}^{{{x^{1}}}} } \right) \in {R^{n}}$$
will be called the phase point, the parameter (point)
$$u = \left( {\mathop{ \vdots }\limits_{{{u^{n}}}}^{{{u^{1}}}} } \right) \in {R^{r}}$$
will be called the control parameter, and the vector
$$f(t,x,u) = \left( {\mathop{ \vdots }\limits_{{{f^{n}}(t,x,u)}}^{{{f^{1}}(t,x,u)}} } \right) \in {R^{n}}$$
will be called the phase velocity vector. We assume that/is a continuous function on
$${R^{{1 + n + r}}} = \left\{ {(t,x,u):t \in {R^{n}},u \in {R^{r}}} \right\}$$
and that it has a continuous derivative with respect to x:
$$\frac{{\partial f(t,x,u)}}{{\partial x}} = \left( {\frac{{\partial f(t,x,u)}}{{\partial {x^{1}}}}, \ldots ,\frac{{\partial f(t,x,u)}}{{\partial {x^{n}}}}} \right)$$
