  • Abstract

    We are interested to the coefficient of the non-linear convection term estimation of the Hamilton-Jacobi equation, in two-dimensional, with the Cauchy-Dirichlet conditions. We validate numerically some properties of the KPZ equation with the same conditions mention above while making a correlation with the surface-growth phenomenon.
