WebA standard proof of Friedrich's second inequality is based on contradiction argumentation. In this paper a direct proof is presented. Moreover, necessary and sufficient conditions for the validity of Friedrichs' first and second inequality are given for plane domains. dc.language.iso: eng: dc.publisher: DENMARK Societates Mathematicae Web216 A.
