Linear Elliptic Systems

Part of the Birkhäuser Advanced Texts / Basler Lehrbücher book series (BAT)


Sometimes, in many physical situations, one has not only to look for a scalar u but for a vector u = (u 1 ,... ,u m ). (In what follows a bold letter will always denote a vector.) This could be a position in space, a displacement, a velocity... So one is in need to introduce systems of equations. The simplest one is of course the one consisting in m copies of the Dirichlet problem, that is to say
$$ \left\{ \begin{gathered} - \Delta u^1 = f^1 in \Omega , \hfill \\ \cdots \cdots \cdots \cdots \hfill \\ - \Delta u^m = f^m in \Omega , \hfill \\ u = \left( {u^1 , \ldots u^m } \right) = 0 on \partial \Omega . \hfill \\ \end{gathered} \right. $$
