Abstract
In this paper we define a Myller configuration in a Finsler space and use some special configurations to obtain results about Finsler subspaces. Let $\small{F^{n}}$ = (M,F) be a Finsler space, with M a real, differentiable manifold of dimension n. Using the pull back bundle $\small{({\pi}^{*}TM,\tilde{\pi},\widetilde{TM})}$ of the tangent bundle $\small{(TM,{\pi},M)}$ by the mapping $\small{\tilde{\pi}={\pi}/TM}$ and the Cartan Finsler connection of a Finsler space, we obtain an orthonormal frame of sections of $\small{{\pi}^{*}TM}$ along a regular curve in $\small{\widetilde{TM}}$ and a system of invariants, geometrically associated to the Myller configuration. The fundamental equations are written in a very simple form and we prove a fundamental theorem. Important lines in a Finsler subspace are defined like special lines in a Myller configuration, geometrically associated to the subspace: auto parallels, lines of curvature, asymptotes. Torse forming vector fields with respect to the Cartan Finsler connection are characterized by means of the invariants of the Frenet frame of a versor field along a curve, and the new notion of torse forming vector fields in the sense of Myller is introduced. The particular cases of concurrence and parallelism in the sense of Myller are completely studied, for vector fields from the distribution $\small{T^m}$ of the Myller configuration and also from the normal distribution $\small{T^p}$.
