Green's first identity proof
Web(2.9) and (2.10) are substituted into the divergence theorem, there results Green's first identity: 23 VS dr da n . (2.11) If we write down (2.11) again with and interchanged, and then subtract it from (2.11), the terms cancel, and we obtain Green’s second identity or Green's theorem 223 VS dr da nn http://www.dha.gov.za/index.php/civic-services/identity-documents

WebJan 2, 2024 · I noticed that if I replace $\Phi(x)$ with $\Delta v$ in the above identity the proof is complete. Now in favor of this substitution I thought that $\Delta v $ could be a fundamental solution of $\Delta(\Delta v)=0 $ if and only if $\Phi(y)=\Delta v(y) $. My question is if this assumption is enough in order to do the above. WebGREEN’S IDENTITIES AND GREEN’S FUNCTIONS Green’s first identity First, recall the following theorem.
