This is a complicated equation, but it can be solved for G.

This is a complicated equation, but it can be solved for G.

<math>G(\mathbf{k},\omega) = \frac{1}{4\pi^2}\frac{1}{c^2k^2-\omega^2}</math>

<math>G(\mathbf{k},\omega) = \frac{1}{4\pi^2}\left(\frac{1}{c^2k^2-\omega^2}\right)</math>

Once G is calculated, we can apply an inverse Fourier transform and find g; we can then plug this into
