Sabau, Sorin V. (ed.) et al., Finsler geometry, Sapporo 2005. In memory of Makoto Matsumoto. Proceedings of the 40th Finsler symposium on Finsler geometry, Sapporo, Japan, September 6–10, 2005.

In the first part of this paper, the author introduces and investigates the dynamical systems of the Lagrangian mechanical system $$\Sigma_{L}=(M,L(x,y),F_{e}(x,y))$$. He proves the existence of a canonical dynamical system on the phase space whose integral curves are given by the Lagrangian equations of $$\Sigma_{L}$$. The interesting particular case of Finslerian mechanical systems is considered. The geometry of $$\Sigma_{L}$$ on $$TM$$ is also described. This part may be considered as a concise survey of various recent works of the author.
In the second part, the author considers the same problem for the Hamiltonian mechanical system $$\Sigma_{H}=(M,H(x,p),F_{e}(x,p))$$. He proves the existence of a canonical dynamical system on the momenta space, whose integral curves are given by the Hamiltonian equations of $$\Sigma_{H}$$. The interesting particular case of Cartan mechanical systems is examined. The second part is entirely original.
