Özet

We consider M-projective curvature tensor on Lorentzian alpha- Sasakian manifolds and show that M-projectively semisymmetric Lorentzian alpha-Sasakian manifold is M-projectively flat. Further, it is shown that, M-projectively semisymmetric Lorentzian alpha-Sasakian manifold is semisymmetric. Finally, some results related to energy momentum tensor satisfying the Einstein field equation with cosmological constant of the M-projectively semisymmetric Lorentzian alpha-Sasakian space-times are investigated.
