Since you mentioned the har inverse problem, I'll complete your answer a bit bu mentioning that the problem of determining when a system of paths---one for every tangent direction---correspond to extremals of a variational problem is quite interesting and goes back to Darboux, Hilbert (his fourth problem, for example), Douglas (3 dimensions), and has been worked on by very many people. There is a huge gap between general results (your boxed theorem) and concrete cases like Hilbert's fourth problem. | |
