We obtain sufficient conditions for a lightlike hypersurface to be pseudosymmetric, pseudoparallel and Ricci-pseudosymmetric in an indefinite Sasakian space form. We also find certain conditions for a pseudosymmetric lightlike hypersurface of an indefinite Sasakian space form to be totally geodesic and check the effect of Weyl projective pseudosymmetry conditions on the geometry of a lightlike hyper surface of an indefinite Sasakian space form. Moreover we give some physical interpretations of pseudo-symmetry conditions.eninfo:eu-repo/semantics/openAccessPseudosymmetric lightlike hypersurfacepseudoparallel lightlike hypersurfaceindefinite Sasakian space formKilling horizonconformal Killing horizonArticle6369971910.11948/20160462-s2.0-84969269046Q2WOS:000385782500006Q3
