We look into a few intriguing properties of para Kenmotsu (also known as p-Kenmotsu) manifolds that satisfy the requirements R(X,Y). R(X,Y) = 0, R(X,Y) = 0, R(X,Y) = 0, R(X,Y P(X,Y) and P(X,Y) P(X,Y) is the Weyl projective curvature tensor of the manifold, and R(X,Y) is the Riemannian curvature tensor. A semi-symmetric p-Kenmotsu manifold (Mn,g) with constant curvature is shown to be a sp-Kenmotsu manifold. We also show that a p-Kenmotsu manifold is projectively flat by obtaining the necessary and sufficient conditions for it to be Weyl projective semi-symmetric. Finally, we show that the condition P(X,Y) is satisfied. When R = 0 on a p-Kenmotsu manifold, the scalar curvature remains constant.
