Multidimensional Dynamical Systems Accepting the Normal Shift

Abstract

The dynamical systems of the form $\ddot\bold r=\bold F (\bold r,\dot\bold r)$ in $\Bbb R^n$ accepting the normal shift are considered. The concept of weak normality for them is introduced. The partial differential equations for the force field $\bold F(\bold r,\dot\bold r)$ of the dynamical systems with weak and complete normality are derived.
