WebMay 24, 2024 · Here the two formulas, called Green's identities, are derived using the Divergence theorem. Green's identities are useful identities for converting integrals with gradients and divergences into integrals with normal derivatives. They are used, for example, in electrostatics to calculate electric potentials. WebJun 29, 2024 · You can apply Green's first identity or just the divergence theorem (pretty much the same thing with the appropriate choice of the fields involved): ∫ M Δ f = ∫ ∂ M ⋯ = 0 since the boundary is empty. Then apply the conditions on f to get Δ f = 0.
