WebThe Greens function must be equal to Wt plus some homogeneous solution to the wave equation. In order to match the boundary conditions, we must choose this homogeneous solution to be the infinite array of image points (Wt itself provides the single source point lying within Ω), giving G(x,y,t) = X n∈Zd Wt(x −y −2πn) (21) WebFigure 5.3: The Green function G(t;˝) for the damped oscillator problem .

WebGreen’s function. The solution of the Poisson or Laplace equation in a finite volume V with either Dirichlet or Neumann boundary conditions on the bounding surface S can be obtained by means of so-called Green’s functions. The simplest example of Green’s function is the Green’s function of free space: 0 1 G (, ) rr rr.

WebBefore solving (3), let us show that G(x,x ′) is really a function of x−x (which will allow us to write the Fourier transform of G(x,x′) as a function of x − x′). This is a consequence of translational invariance, i.e., that for any constant a we have G(x+a,x′ +a) = G(x,x′). If we take the derivative of both sides of this with WebGreen’s functions appear naturally in many perturbative calculations. We have seen an example in Sections 3.1.6 and 3.1.7, where ha+(x)a(y)imay be interpreted as equal-time Green’s functions. However, if we choose to extend the calculations of Section 3.1.7 to higher orders in interaction, we would need to introduce time-dependent (or ...
