Green's third identity
Green's third identity states that if ψ is a function that is twice continuously differentiable on U, then. A simplification arises if ψ is itself a harmonic function, i.e. a solution to the Laplace equation. Then ∇2ψ = 0 and the identity simplifies to. 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, … See more 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 … 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 … 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.

Here’s an explanation of how ID graphs work: Step 1. Data collection: A company would send its customer IDs (i.e. first-party IDs) to the ID graph. These first-party IDs could be taken from websites, mobile apps, and customer and data platforms (e.g. CRMs, CDPs, and DMPs). Step 2.
