摘要
In the present paper, we introduce a new class of natural metrics on the tangent bundle TM of the Riemannian manifold (M, g) denoted by G(f,h) which is named a twisted Sasakian metric. A necessary and sufficient conditions under which a vector field is harmonic with respect to the twisted Sasakian metric are established. Some examples of harmonic vector fields are presented as well.
