We calculate all Riemannian curvature tensor fields of the deformed Sasaki metric ¯g and search Einstein property of T2M. Also the weakly symmetry properties of the deformed Sasaki metric are presented.trSecond-order tangent bundle, deformed Sasaki metric, weakly symmetric, curvature tensor field, liftsArticle7125025171303-5991
