SBV regularity for Hamilton-Jacobi equations in $\mathbb R^n$

In this paper we study the regularity of viscosity solutions to the following Hamilton-Jacobi equations $\partial_t u + H(D_{x} u)=0 \qquad \textrm{in} Ω\subset \mathbb R\times \mathbb R^{n} .$ In particular, under the assumption that the Hamiltonian $H\in C^2(\mathbb R^n)$ is uniformly convex, we prove that $D_{x}u$ and $\partial_t u$ belong to the class $SBV_{loc}(Ω)$.
