Webthe Green's function is the solution of. (12) L [ G ( r, r ′)] = δ ( r − r ′) Therefore, the Green's function can be taken as a function that gives the effect at r of a source element located at r’. An example with electrostatic potentials will be used for illustrative purposes. The primary use of Green's functions in mathematics is to solve non-homogeneous boundary value problems. In modern theoretical physics, Green's functions are also usually used as propagators in Feynman diagrams; the term Green's function is often further used for any correlation function. Let be the Sturm–Liouville operator, a linear differential operator of the form
WebJan 12, 2015 · 0. I have a conducting plate on x - y plane. So I have a boundary condition at z = 0 Φ = 0 but, for z > 0 I have a point charge at z=a which is expected to create a potential. ∇ 2 Φ = ρ ε 0. I need a Green function which can be assigned as : G ( r, r ′) = 1 ( x − x ′) 2 + ( y − y ′) 2 + ( z − a) 2 . But this Green function ... WebMore General Spherical Green's Function Problems. This method will work for situations where the image technique is much messier. For example, suppose the charge is between two grounded conducting concentric spheres, so a < r, r ′ < b. This will need an infinite series of images. But by the present method, it is straightforward.
