Green's function in simple
WebInformally speaking, the -function “picks out” the value of a continuous function ˚(x) at one point. There are -functions for higher dimensions also. We define the n-dimensional -function to behave as Z Rn ˚(x) (x x 0)dx = ˚(x 0); for any continuous ˚(x) : Rn!R. Sometimes the multidimensional -function is written as a WebGreen's Function Integral Equation Methods in Nano-Optics.

(9.170) Notice that the Green’s function is a function of t and of T separately, although in simple cases it is also just a function of tT. This may sound like a peculiar thing to do, but the Green’s function is everywhere in physics. An
