We study hypersurfaces in the Lorentz-Minkowski space L n+1 whose position vector ψ satisfies the condition L k ψ = Aψ + b, where L k is the linearized operator of the (k + 1)th mean curvature of the hypersurface for a fixed k = 0, . . . , n − 1, A ∈ R (n+1)×(n+1) is a constant matrix and b ∈ L n+1 is a constant vector. For every k, we prove that the only hypersurfaces satisfying that condition are hypersurfaces with zero (k + 1)th mean curvature, open pieces of totally umbilical hypersurfaces S n 1 (r ) or H n (−r ), and open pieces of generalized cylinders S mThis completely extends to the Lorentz-Minkowski space a previous classification for hypersurfaces in R n+1 given by Alías and Gürbüz (Geom. Dedicata 121:113-127, 2006).
