Euler Equations for Variational Problems in Homogeneous Spaces,It is well-known that a general curve γ⊂IE. has a Frenet frame.

Endpoint Conditions; Jacobi Equations and the 2nd Variation; the Hamilton-Jacobi Equation,We consider a variational problem (I, ω; φ) with one independent variable on a manifold X.

Preliminaries,the point p is T.(M), and the tangent bundle is .. We sometimes write points in T(M) as (p, v) where p∈M and v∈T.(M). A local coordinate system (x. ) on M induces a local coordinate system . on T(M) where p has coordinates (x.,...,x.) and .. ..
