The result is ZZZ D (u∆v −v∆u)dV = ZZ ∂D u ∂v ∂n −v ∂u ∂n dS. (3) This is Green’s second identity. It is valid for any general (need not be harmonic) pair of functions u and v.

WebThe Green’s second identity for vector functions can be used to develop the vector-dyadic version of the theorem. For any two vector functions P and Qjwhich together with their ﬁrst and second derivatives are continuous it can be shown that4 ZZ v Z [P ·∇×∇×Qj−(∇ ×∇×P)· Q ]dv = ZZ [Qj×∇×P −P ×∇×Q ]· ˆnds (12) = ZZ s [(∇ ×P × ˆn) ·Qj+P ·(ˆn×∇×Qj)]ds 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 invokes the divergence of a cross product and states … 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.
