چکیده
In this paper, we study Ricci semi-symmetric null hypersurfaces in a Lorentzian space form. We give a necessary and sufficient condition for a screen quas-conformal null hypersurface to be Ricci semi-symmetric. We show that every screen quasi-conformal null hypersurface M of R1m+2 such that rank *Aξ < m is Ricci semi-symmetric. Next, we give a local classification of a Ricc semi-symmetric screen conformal null hypersurface of a Lorentzian space form.
