Query: On the use of connections in the calculus of variations in Finsler
  geometry   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.
