Some properties of LP-Sasakian manifolds admitting a quarter symmetric non metric connection

The object of the present paper is to study weakly symmetric, weakly Ricci symmetric, generalized recurrent and generalized Ricci recurrent LP-Sasakian manifolds admitting a quarter symmetric non metric connection [nabla]. Keywords and Phrases: Quarter-symmetric non metric connection, LP-Sasakian manifolds, Weakly symmetric, Weakly Ricci symmetric, Generalized recurrent, Generalized Ricci recurrent.
1. Introduction The idea of metric connection with torsion tensor in a Riemannian manifold was introduced by Hayden [19]. Later, Yano [11] studied some properties of semi symmetric metric connection [...]
