Abstract: Consider the differential inclusion $Du\in E$ in $\mathbb{R} ^{n}$ . We exhibit an explicit solution that we call fundamental. It also turns out to be a viscosity solution when properly defining this notion. Finally, we consider a Dirichlet problem associated to the differential inclusion and we give an iterative procedure for finding a solution.
