Abstract: In this paper, we study some properties of ruled surfaces with non-degenerate second fundamental form in a 3-dimensional Lorentz-Minkowski space related to its the Gaussian curvature, the second Gaussian curvature and the mean curvature.
Keywords: Gaussian curvature, second Gaussian curvature, mean curvature, ruled surface, minimal surface.
