Green's first identity proof

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.
