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

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

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

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