Abstract

In this paper we study isometries of ruled surfaces in the Lorentz-Minkowski space that preserve rulings. A special attention is given to the classes of surfaces having no Euclidean counterparts. We also construct some examples of isometric ruled surfaces with certain properties and rulings preserved.

Keywords

Lorentz-Minkowski space; isometry; ruled surface; B-scroll.
