Some Results on Tangent Bundles with Berger Type Deformed Sasaki Metric over Kählerian Manifolds
Let $M$ be a Kählerian manifold equipped with an almost complex structure $J$ and a Riemannian metric $g$, and let $TM$ be its tangent bundle with the Berger type deformed Sasaki metric. In this paper, firstly, we find all forms of Riemannian curvature tensors of $TM$. Secondly, we search the condit...

In this paper, firstly, we find all forms of Riemannian curvature tensors of $TM$. Secondly, we search the conditions under which a vector field is harmonic with respect to the Berger type deformed Sasaki metric and give some examples of harmonic vector fields. Finally, we study the harmonicity of maps between the Riemannian manifold and the tangent bundle of another Riemannian manifold and vice versa.
