WebThe Greens reciprocity theorem is usually proved by using the Greens second identity. Why don't we prove it in the following "direct" way, which sounds more intuitive: ∫ all space ρ ( r) Φ ′ ( r) d V = ∫ all space ρ ( r) ( ∫ all space ρ ′ ( r ′) r − r ′ d V ′) d V.

WebThe advantage is thatﬁnding the Green’s function G depends only on the area D and curve C, not on F and f. Note: this method can be generalized to 3D domains - see Haberman. 2.1 Finding the Green’s function Ref: Haberman §9.5.6 To ﬁnd the Green’s function for a 2D domain D (see Haberman for 3D domains), WebSep 8, 2016 · I am also directed to use Green's second identity: for any smooth functions f, g: R 3 → R, and any sphere S enclosing a volume V, ∫ S ( f ∇ g − g ∇ f) ⋅ d S = ∫ V ( f ∇ 2 g − g ∇ 2 f) d V. Here is what I have tried: left f = ϕ and g ( r) = r (distance from the origin). Then ∇ g = r ^, ∇ 2 g = 1 r, and ∇ 2 f = 0.
