Query: A distinguished geometry perspective on multi-time affine quadratic
  Lagrangians   For a space endowed with a general quadratic multi-time Lagrangian and an
associated non-linear connection, the paper constructs the main
Riemann-Lagrange distinguished geometric objects (linear connection, torsion
and curvature).
