It is known in partial differential equations theory in higher dimensions that at boundary points where \(\sum {_{i,j}\sigma }^{ij}{(\mbox{ $\boldsymbol{x}$})\nu }^{i}{(\mbox{ $\boldsymbol{x}$})\nu }^{j}(\mbox{ $\boldsymbol{x}$}) = 0\) , boundary conditions can be imposed only at points where \(\mbox{ $\boldsymbol{a}$}(\mbox{ $\boldsymbol{x}$}) \cdot \mbox{ $\boldsymbol{\nu }$}(\mbox{ $\boldsymbol{x}$}) < 0\) (Fichera 1960).
