The Berwald-Moor metric in the tangent bundle of the second order
2005jbo | Gheorghe Atanasiu, Nicoleta Brinzei

As an application of the results of the first author obtained in the papers \cite{1} and \cite{2}, the geometry of the second order tangent bundle $% T^{2}M$ (or second order jet bundle $J_{0}^{2}M$) endowed with two special types of metrics compatible with the 2-contact structures is studied. The particularity of these two models is that the horizontal and the $v^{(1)}$-\ part of the metric are both given by the same Riemannian metric (respectively, its horizontal part is Riemannian), while its $v^{(2)}$-part is given by the flag-Finsler Berwald-Moor metric (respectively, the $v^{(1)} $ and $v^{(2)}$- parts are given by the flag-Finsler Berwald-Moor metric, \cite{Mangalia}).
