LS - SASAKIAN MANIFOLD S WITH SEMI - SYMMETRIC NON - METRIC CONNECTION

In 1976, I. Sato [4] introduced a structure similar to almost contact structure. Also in 1977, I. Sato [5] discussed on a structure similar to almost contact structure II. In 1977, T. Adati and K. Matsumoto [1] discussed on conformally recurrent and conformally symmetric p - Sasakian manifolds. Also in 1979, K. Matsumoto and I. Sato [2] discussed on p - Sasakian manifolds with certain conditions. The purpose of this paper is to study Lorentzian special Sasakian manifolds and generalized Lorentzian Co - symplectic manifolds with s emi - symmetric non - metric connection [ 3].
