Homework Statement
I'm reading through Jackson and ran into the following:
An application of Gauss's theorem to
∇'[itex]^{2}[/itex]G=-4πδ(x-x')
shows that
[itex]\oint[/itex]([itex]\partial[/itex]G/[itex]\partial[/itex]n')da'= -4∏
where G is a Green function given by 1/|x-x'| + F, and F is a function whose Laplacian is zero.
(Sec. 1.10, Formal Solution of Electrostaic Boundary Value Problem)
Homework Equations
Divergence theorem?
Gauss's theorem?
The Attempt at a Solution
I don't see how to arrive at the surface integral. This looks a bit like an application of the divergence theorem because of the surface integral term. It also looks something like Gauss's law in differential form. Is this what the author means by applying Gauss's theorem?
