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, who discovered Green's theorem. 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 functions defined on some region U ⊂ R , and … 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 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 case of ε = 1 all across U ⊂ R , then, In the equation … See more Green's identities hold on a Riemannian manifold. In this setting, the first two are See more Green's second identity establishes a relationship between second and (the divergence of) first order derivatives of two scalar functions.
