Domain decomposition procedure: a the classic one, when \(\Omega \) is decomposed into local and complementary sub-domains \(\Omega _L\) and \(\Omega _C\), respectively, which do not overlap and are coupled by the interface \(\Gamma \); b its extension to the global/local setting, where a fictitious domain \(\Omega _F\) is introduced to form the so-called global domain \(\Omega _G:=\Omega _C\cup \Gamma \cup \Omega _F\)
