摘要：
Lorentz hypersurfaces M4 1 is studied in E5 1 with non-diagonal shape operators having characteristic equation oy kTHORN2 oy k3THORNoy k4THORN or oy kTHORN3 oy k4THORN or ooy kTHORN2 thorn l2THORNoy k3THORNoy k4THORN. It is proved that if the mean curvature vector field H of Lorentz hypersurfaces M4 1 in E5 1 with non-diagonal shape operators satisfies the equation MH 1/4 aH (for a constant a), then M4 1 has constant mean curvature.
