## Abstract

top
We formulate an Hamilton-Jacobi partial differential equation$H\left(x,Du\left(x\right)\right)=0$on a $n$ dimensional manifold $M$, with assumptions of convexity of $H\left(x,·\right)$ and regularity of $H$ (locally in a neighborhood of $\left\{H=0\right\}$ 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 ${ℋ}^{n-1}$ negligeable subset. These results can be applied to the cutlocus of a ${C}^{2}$ submanifold of a Finsler manifold.
