TLDR
In this article, the regularity of viscosity solutions to the Hamilton-Jacobi equation was studied under the assumption that the Hamiltonian is uniformly convex, and it was shown that the class SBV isEnabled loc (Ω) belongs to the class of SBV▬▬▬▬▬▬▬ ǫ.Abstract:
In this paper we study the regularity of viscosity solutions to the following Hamilton–Jacobi equations $$\partial_{t}u+H(D_{x}u)=0\quad\hbox{in }\Omega\subset{\mathbb R}\times{\mathbb R}^{n}.$$
In particular, under the assumption that the Hamiltonian $${H\in C^2({\mathbb R}^n)}$$
is uniformly convex, we prove that D

SBV Regularity for Hamilton--Jacobi Equations with Hamiltonian Depending on $(t, x)$

TL;DR: This result extends the result of Bianchini, De Lellis, and Robyr obtained for a Hamiltonian $H=H(D_x u)$ which depends only on the spatial gradient of the solution to prove the special bounded variation regularity of the gradient of a viscosity solution of the Hamilton--Jacobi equation.

Two-dimensional unit-length vector fields of vanishing divergence
TL;DR: In this paper, it was shown that any two-dimensional unit-length divergence-free vector field belonging to W 1 / p, p (p ∈ [ 1, 2 ] ) is locally Lipschitz except at a locally finite number of vortex-point singularities.
