Abstract
Let χ and y be affine connection spaces with the connections ∇χ and ∇y (to simplify formulas, we often write ∇ instead of ∇χ and \(\hat \nabla \) instead of ∇y). On each coordinate neighborhood U of the manifold χ (coordinate neighborhood V of the manifold y), the connection ∇χ (connection ∇y) is given by the matrix ω = ω x (matrix \(\hat \omega \)= ω y) of connection forms. The connection ∇x sets the horizontal subspace H x A of the tangent space T A (T χ) in correspondence with each tangent vector A (point of the total space T χ of the tangent bundle τx). Similarly, the connection ∇y sets the horizontal subspace H y B ⊂ T B (T y) in correspondence with each point B ∈ T y.
