Abstract

We study some differential properties of viscosity solution for Hamilton - Jacobi equations defined by Hopf-Lax formula u(t,x)=minyRn{σ(y)+tH(xyt)}.u(t,x)=\min_{y\in \R^n} \big\{\sigma (y)+tH^*\big (\frac {x-y}{t}\big)\big \}. A generalized form of characteristics of the Cauchy problems is taken into account the context. Then we examine the strip of differentiability of the viscosity solution given by the function u(t,x).u(t,x).
