Help with Green's function

  1. Jul 4, 2010 #1
    I have a serious blind-spot with mathematics (but I keep trying)
    Can someone help me with this.

    I have a relation [tex]A = \mu_{0}/4\pi\int J/r \ dVol[/tex]

    Which (apparently!) can be written [tex]\nabla^{2} A = - \mu_{0} J[/tex]

    I know that [tex]\nabla^{2} A = 1/r \ \delta^{2} ( r A ) / \delta r^{2}[/tex]
    which is the polar form of the Laplace operator

    but I can't see how to use it to make the step.
    The text refers to it as a Green's function but the explanations of that phrase look like a it would take me days to figure out what that means.
    Is there a simple explanation?
