calculus - Divergence theorem and Green
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 identity states that if ψ is a function that is twice continuously … 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 … See more • Green's function • Kirchhoff integral theorem • Lagrange's identity (boundary value problem) See more • "Green formulas", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • [1] Green's Identities at Wolfram MathWorld 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 suppose that φ is twice continuously differentiable See more Green's identities hold on a Riemannian manifold.
