Geodesic equals energy minimum: Difference between revisions

Revision as of 10:16, 5 August 2007

Let $M$ be a complete Riemannian manifold and $p, q \in M$ be any two points in $M$ at distance $d$ . Then, the energy functional on the path space $Ω (M; p, q)$ attains its minimum value $d^{2}$ precisely on the minimal geodesics from $p$ to $q$ .
