On the connection of geometric properties of curves and properties of their motion groups
E. A. Rogozinnikov Ural State University
Abstract:
Connections between geometric properties of curves and properties of their motion groups are established. Motions of two types, namely, positive and negative motions, are defined for curves. A necessary and sufficient condition for a smooth curve to possess a motion of one of these types is given. The notion of a motion group of a curve is defined in different ways, and classes of curves are specified for which these notions coincide. Closed curves are investigated in terms of their motion groups, and a necessary and sufficient condition for a smooth curve to be closed is presented.
Keywords:
curve, image of a curve, motion, group of motions, curvatures of a curve, closedness of a curve.
