f-Biharmonic and Bi-f-Harmonic Magnetic Curves in Three-Dimensional Normal Almost Paracontact Metric Manifolds

Abstract

In this paper, we study f-harmonic, f-biharmonic, bi-f-harmonic and f-biminimal non-null magnetic curves in three-dimensional normal almost paracontact metric manifolds. We determine necessary and sufficient conditions for these properties of a non-null magnetic curve. Besides, we obtain absence theorems.
