Abstract
We propose a unified approach to the theory of connections in the geometry of sprays and Finsler metrics which, in particular, gives a simple explanation of the well-known fact that all the classical Finslerian connections provide exactly the same formulas appearing in the calculus of variations.
We’re sorry, something doesn't seem to be working properly.
Please try refreshing the page. If that doesn't work, please contact support so we can address the problem.
Notes
We refer to Grifone (1972) for the definition of a symmetric connection.
Here, \([S,\mathscr {J}]\) stands for the Lie derivative of the tensor field \(\mathscr {J}\) along S.
