Query: Alternatives to Eisenhart lift in Randers-Finsler geometry   In this article I discuss two alternatives to Eisenhart lift in
Randers-Finsler geometry. I first cover preliminaries of mechanics, discussing
Maupertuis principle and the constraint. Then I review the Eisenhart lift,
demonstrate its limitations, and discuss the Jacobi metric, introducing Jacobi
lift and Symmetry Replacement. I conclude by discussing the optical metric in
this context, and the advantage of such alternatives in the study of
Randers-Finsler gravity.
