Lie derivatives of almost contact structure and almost paracontact structure with respect to...

The differential geometry of tangent bundles was studied by several authors, for example: D. E. Blair B76, V. Oproiu O73, A. Salimov S13, Yano and Ishihara YI73 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. Our goal is to study Lie derivatives of almost contact structure and almost paracontact structure with respect to X^{C} and X^{V} on tangent bundle T(M). In addition, this Lie derivatives which obtained shall be studied for some special values.
