We discuss rst @ tu+ H(ru) = 0; (1) where H(p) is convex, and superlinear at in nity, lim jpj!1 H(p) jpj = +1 This by comes by integration from special hyperbolic systems of the form (n= m) @ tv+ F j(v)@ jv= 0 when there exists a pontental for F j, i.e. F j = @ jH ... WebSolution of the H-J equation. Now we show that the Hopf-Lax formula u(x,t)= inf y∈ Rn n tL x − y t + g(y) o. (35) indeed solves the Hamilton-Jacobi equation, albeit only “almost everywhere”. Remark 4. It is easy to see that in general one cannot expect the existence of classical solutions due to possible intersections of characteristics.
