We introduce and study a subclass Σ P γ, k, λ, c of meromorphic univalent functions defined by certain linear operator involving the generalized hypergeometric function. We obtain coefficient estimates, extreme points, growth and distortion inequalities, radii of meromorphic starlikeness, and convexity for the class Σ P γ, k, λ, c by fixing the second coefficient. Further, it is shown that the class Σ P γ, k, λ is closed under convex linear combination.

We study the geometry of Kenmotsu manifolds when the conformal, con circular and con harmonic curvature tensors are conservative.

The object of this paper is study (ε)-para-Sasakian 3-manifolds satisfying certain conditions on the Z tensor. We characterize: Z-symmetric, Z-semisymmetric, Z-pseudosymmetric, and projectively Z-semisymmetric conditions on an (ε)-para-Sasakian 3-manifold.
