http://people.uncw.edu/hermanr/pde1/pdebook/green.pdf Green's second identity establishes a relationship between second and (the divergence of) first order derivatives of two scalar functions. In differential form In vector diffraction theory, two versions of Green's second identity are introduced. One variant invokes the divergence of a cross product and states … See more In mathematics, Green's identities are a set of three identities in vector calculus relating the bulk with the boundary of a region on which differential operators act. They are named after the mathematician George Green, … See more If φ and ψ are both twice continuously differentiable on U ⊂ R , and ε is once continuously differentiable, one may choose F = ψε ∇φ − φε ∇ψ to obtain For the special … See more Green's identities hold on a Riemannian manifold.

Why don't we prove it in the following "direct" way, which sounds more intuitive: ∫ all space ρ ( r) Φ ′ ( r) d V = ∫ all space ρ ( r) ( ∫ all space ρ ′ ( r ′) r − r ′ d V ′) d V.
