Union Curves of a Hypersurface

Canadian Journal of Mathematics, 1950
1. Introduction. A curve on an ordinary surface is a union curve if its osculating plane at each point contains the line of a specified rectilinear congruence through the point. The author has obtained the differential equations of union curves on a metric surface in ordinary space and has exhibited certain generalizations for union curves of known ...
