Tachibana and Vishnevskii operators applied to X^V and X^H in almost paracontact structure on tangent bundle T(M)

The differential geometry of tangent bundles was studied by several authors, for example: Yano and Ishihara YI73, V. Oproiu O73, A.A. Salimov S13, D. E. Blair B76 and among others. It is well known that differant structures deffined on a manifold M can be lifted to the same type of structures on its tangent bundle. In addition, several authors was studied on operators too, for example: A.A. Salimov S13. Our goal is to study Tachibana and Vishnevskii Operators Applied to X^V and X^H in almost paracontact structure on tangent bundle T(M). In addition, this results which obtained shall be studied for some special values in almost paracontact structure.
