Webi.e. ∫ ∫ Ω ∇ f ⋅ ∇ g d A + ∫ ∫ Ω f ( Δ g) d A = ∫ ∂ Ω f ∇ g ⋅ n d s. which is Green's first identity. To derive Green's second identity, write Green's first identity again, with the roles of f and g … 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 Green's third identity derives from the second identity by choosing φ = G, where the Green's function G is taken to be a fundamental solution of the Laplace operator, ∆. This means that: For example, in R , a solution has the form Green's third … See more • Green's function • Kirchhoff integral theorem • Lagrange's identity (boundary value problem) See more This identity is derived from the divergence theorem applied to the vector field F = ψ ∇φ while using an extension of the product rule that ∇ ⋅ (ψ X ) = ∇ψ ⋅X + ψ ∇⋅X: Let φ and ψ be scalar … 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 … See more Green's identities hold on a Riemannian manifold.

Theorems such as this can be thought of as two-dimensional extensions of integration by parts. Green published this theorem in 1828, but it was known earlier to Lagrange and Gauss. hillary watts
