Abstract
We consider the unit tangent sphere bundle of Riemannian
manifold (M, g) with g-natural metric ˜G and we equip it to an almost
contact B-metric structure. Considering this structure, we show that
there is a direct correlation between the Riemannian curvature tensor of
(M, g) and local symmetry property of ˜G. More precisely, we prove that
the flatness of metric g is necessary and sufficient for the g-natural metric
˜G
to be locally symmetric.
