Ricci Solitons in α‐Sasakian Manifolds
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 We study Ricci solitons in α‐Sasakian manifolds. It is shown that a symmetric parallel second order‐covariant tensor in a α‐Sasakian manifold is a constant multiple of the metric tensor. Using this, it is shown that if ℒVg + 2S is parallel where V is a given vector field, then (g, V, λ) is Ricci soliton.

Slant curves in 3-dimensional normal almost paracontact metric manifolds
, 2012 The presented paper is devoted to study the curvature and torsion of slant Frenet curves in 3-dimensional normal almost paracontact metric manifolds. Moreover, in this class of manifolds, properties of non- Frenet slant curves (with null tangents or null

Harmonic (p, q)‐Curves in Trans‐Sasakian and Normal Almost Paracontact Metric Manifolds
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this paper, we give some characterizations about biharmonic, f‐harmonic, and f‐biharmonic (p, q)‐curves in 3‐dimensional trans‐Sasakian and normal almost paracontact metric manifolds. The (p, q)‐curves are considered as generalizations of magnetic curves.
