AB - We formulate an Hamilton-Jacobi partial differential equation\[ H( x, D u(x))=0\]on a $n$ dimensional manifold $M$, with assumptions of convexity of $H(x,\cdot )$ and regularity of $H$ (locally in a neighborhood of $\lbrace H=0\rbrace $ in $T^*M$); we define the “min solution” $u$, a generalized solution; to this end, we view $T^*M$ as a symplectic manifold. The definition of “min solution” is suited to proving regularity results about $u$; in particular, we prove in the first part that the closure of the set where $u$ is not regular may be covered by a countable number of $n-1$ dimensional manifolds, but for a ${\mathcal {H}}^{n-1}$ negligeable subset. These results can be applied to the cutlocus of a $C^2$ submanifold of a Finsler manifold.
