Green's second identity
WebGreen’s second identity relating the Laplacians with the divergence has been derived for vector fields. No use of bivectors or dyadics has been made as in some previous approaches. WebGreen’s second identity Switch u and v in Green’s first identity, then subtract it from the original form of the identity. The result is ZZZ D (u∆v −v∆u)dV = ZZ ∂D u ∂v ∂n −v ∂u ∂n …
