Green's function method
WebThe function g(x, s) is called Green's function, and is completely associated with the problem Ly = d2y dx2 + p(x)dy dx + q(x)y = f(x), By = ( y(a) y ′ (a)) = (0 0), a < x < b The Green's functions is some sort of "inverse" of the operator L with boundary conditions B. What happens with boundary conditions on a and b? WebApr 27, 2015 · Now Greens function is just the solution to ∇2G(x xs) = δ(x − xs) with x = (x, y) and xs = (xs, ys). In complex notation let z = x + iy and zs = xs + iys. In our half plane the method of images gives: G(ζ ζs) = − 1 2π(ln( ζ − ζs ) − ln( ζ − ¯ ζs )) where the bar denotes complex conjugate.
