Query: An account on links between Finsler and Lorentz Geometries for
  Riemannian Geometers   Some links between Lorentz and Finsler geometries have been developed in the
last years, with applications even to the Riemannian case. Our purpose is to
give a brief description of them, which may serve as an introduction to recent
references. As a motivating example, we start with Zermelo navigation problem,
where its known Finslerian description permits a Lorentzian picture which
allows for a full geometric understanding of the original problem. Then, we
develop some issues including: (a) the accurate description of the Lorentzian
causality using Finsler elements, (b) the non-singular description of some
Finsler elements (such as Kropina metrics or complete extensions of Randers
ones with constant flag curvature), (c) the natural relation between the
Lorentzian causal boundary and the Gromov and Busemann ones in the Finsler
setting, and (d) practical applications to the propagation of waves and
firefronts.
