\nabla \cdot \left (\mathbf a \times \boldsymbol \omega \right ) = - \frac{1}{2}\frac{1}{c^2}\frac{\partial \mathbf a \cdot \mathbf a}{\partial t} -  \frac{1}{2}\frac{\partial \boldsymbol \omega  \cdot \boldsymbol \omega }{\partial t} - \frac{G}{c^2}\rho\mathbf v \cdot \mathbf a = -  G\rho H_0

\mathbf j = \left (\mathbf a \times \boldsymbol \omega \right )

\boldsymbol \varepsilon = \nabla \times \mathbf a

\nabla \cdot \left (\mathbf j \times \boldsymbol \varepsilon \right ) = - \frac{1}{2}\frac{1}{c^2}\frac{\partial \mathbf j \cdot \mathbf j}{\partial t} -  \frac{1}{2}\frac{\partial \boldsymbol \varepsilon \cdot \boldsymbol \varepsilon  }{\partial t} - \frac{G}{c^2}\rho\mathbf a \cdot \mathbf j = -  G\rho H_0^3
