Problemi al contorno per sistemi ellittici del primo ordine a coefficienti costanti in aperti di classe $C¹$

Abstract

In this paper boundary value problems are studied for symmetrical first order elliptic systems of linear partial differential equations with constant coefficients,in an open subset $ω$ of $R^m(m≥ 3)$. $ω$ is assumed to be of class $C¹$ with boundary data in $L^s(\partial ω)(2≤ s < +∈fty)$.
