Photon green function
WebSomething's very wrong with your differential equation for the Green's function D μ ν. Namely, the LHS is a scalar (-valued function), whereas the δ ν μ makes the RHS into a matrix (-valued function). I have taken the liberty to correct the formula; if I've screwed it up, I apologize. – Theo Johnson-Freyd Dec 1, 2009 at 4:13 Add a comment 3 Answers WebApr 10, 2016 · Green's function, also called a response function, is a device that would allow you to deal with linear boundary value problems (in the literature there are also Green's functions for the initial value problem, but let me stick to the most classical picture). @achillehiu gave a good example. Let me elaborate on it.
