Ruled surfaces of Weingarten type in Minkowski 3-space. II (Q2490666)

This paper is a continuation of a previous paper of the same title [J. Geom. 83, No. 1--2, 10--21 (2005; Zbl 1094.53005)]. The authors study ruled surfaces of Weingarten type \(M:x(s,t)=\alpha (s)+t\beta (s)\) in Minkowski 3-space with vector fields \(\beta\) and \(\beta^{\prime}\) along the base curve \(\alpha\) such that \(\beta\) is nowhere null but \(\beta^{\prime}\) is null everywhere. The authors give a complete classification for such ruled surfaces in Minkowski 3-space.
