Abstract: |
We establish a direct proof of the well known equivalence between the Crandall-Lions viscosity solution of the Hamilton-Jacobi equation  and the Kruzkov-Vol'pert entropy solution of conservation law  . To reach at the purpose we work directly with defining entropy and viscosity inequalities, and using the front tracking method, and do not, as is usually done, exploit the convergence of the viscosity method.
