Equiform kinematics and the geometry of line elements

Boris Odehnal, Helmut Pottmann and Johannes Wallner

Institut für Diskrete Mathematik und Geometrie, TU Wien, Wiedner Hauptstr. 8--10/104, A-1040 Wien, Austria

Abstract: The present paper studies Plücker coordinates for line elements in Euclidean three-space. The well known relation between line geometry and kinematics is generalized to equiform motions and the geometry of line elements. We consider bundles and linear complexes of line elements and survey their properties.

Keywords: line geometry, line element, linear complex, spiral motion, equiform kinematics.

Classification (MSC2000): 51M30, 53A17
