On a type of \(P\)-Sasakian manifold

1992
Let \(M\) be a \(P\)-Sasakian manifold in the sense of \textit{I. Satō} [cf. Tensor, New Ser. 30, 219-224 (1976; Zbl 0344.53025)]. Let \(P\) be the Weyl projective curvature tensor of \(M\). It is proved that if \(R(X,Y) \cdot P = 0\), then \(P = 0\). Consequently, \(M\) is of constant negative curvature and \(SP\)-Sasakian.

On a type of \(P\)-Sasakian manifold

1994
Let \(M\) be a Riemannian manifold with a \(P\)-Sasakian structure \(\Sigma=(\phi,\xi,\eta, g)\). There is a tensor field \(W_2\) of type (1,3) on \(M\) defined as \[ g(W_2(X,Y)Z,U)=g(R(X,Y)Z,U)+\tfrac1{n-1}[g(X,Z)S(Y,U) -g(Y,Z)S(X,U)], \] where \(R\) and \(S\) are curvature and Ricci tensors on \(M\).

Sasakian and Cosymplectic Manifolds

2002
In this chapter we define the normality of an almost contact structure and the notion of a Sasakian manifold as a normal contact metric manifold. We also introduce another important structure tensor, h, which will be useful in the study of non-Sasakian contact metric manifolds.
