Several Tensor Fields in Para-Sasakian Manifolds I

0 Intro(ctionWe introduced fundaental tensor fields and studied their relationships in special para-Sasakian manifolds from the standpoint of the Z)-conformal chage 12310 In this paper we shall treat corresponding tensor fields in a para-Sasakian manifold First in 1 we recall the notions of a para-Sasakian manifold a distribution D defined by a Pfaffian equation O and the integra1anifold of 0 In 2 we find several tensor fields in a para-Sasakian lnanifold which is not a special para-Sasakiamanifold and in 3 we treat the special case In 4 we study the relationships between these tensor fields and the Weyls conformal curvature tensor Finally in 5 we cons ider Z)-homothetic vector fields in a para-Sasakian manifold 1 Apara-Sasakian manifold and a D-conformal change Let M be an n-dimensional differentiable manifold with a poSive definite Riemalian metric g which admits a unit 1-form satisfying (11)i-inki92ki
