De Lellis, Camillo; Ignat, Radu (2015). A regularizing property of the 2D-eikonal equation. Communications in Partial Differential Equations, 40(8):1543-1557.
We prove that any 2-dimensional solution $\psi \in \mathit{W}^{1+^{1}_{3},3}_\mathit{loc}$ of the eikonal equation has locally Lipschitz gradient $\nabla$$\psi$ except at a locally finite number of vortex-points. A related regularizing effect is also obtained for general solutions of the Burgers’ equation.
