Normal Ve Rectifying Curves in the Equiform Differential Geometry of G_3 

Some notes on almost paracomplex structures associated with the diagonal lifts and operators on cotangent bundle

“…The tangent bundles of differentiable manifolds are very important in many areas of mathematics, physics and different topics of geometry (see [3,13,14,17,26] for curves etc.). The geometry of tangent bundles goes back to the fundamental paper [24] of Sasaki published in 1958.…”
