WebGreen’s identities Based on the divergence theorem, we can now derive the Green’s identities. We start with the first Green’s identity. Let u and v be scalar functions with u continuously differentiable and v twice continuously differentiable. Choose F = u ∇ v. From the product rule of differentiation it follows that WebHere, the tool that we used is the divergence theorem (with which is actually derived the Green's first identity). Note that the surface integral is 0 because v is zero on ∂ Ω (to be more speciffic, it is zero in the trace sense).
