Description	Invariance under reparametrizations of integral curves of higher order di?erential equations, including variational equations related to Finsler geometry, is studied. The classical homogeneity concepts are introduced within the theory of (jet) differential groups, known in the theory of differential invariants. On this basis the well-known generalizations of the Euler theorem are obtained (the Zermelo conditions). It is shown that every integral curve of a system of differential equations whose left-hand sides are higher order positive homogeneous functions, is invariant with respect to all reparametrizations, i.e. a set solution. Then the positive homogeneity concept is applied to second order variational equations. We show that the systems with positive homogeneous Lagrangians are de?ned by positive homogeneous functions, and vice versa.
