Tarafdar, Debasish; De, U. C. On a type of P-Sasakian manifold. (English) Zbl 1020.53029 Extr. Math. 8, No. 1, 31-36 (1993). The authors show: If a P-Sasakian manifold is Ricci-semi-symmetric, then it is Einstein; if it is semi-symmetric, then it has constant curvature. They also consider P-Sasakian manifolds which are hypersurfaces of a Riemannian manifold of constant curvature \(1\).
