Key Equations

$$R_{\mu\nu} = R^\rho_{\ \mu\rho\nu} = g^{\rho\sigma} R_{\rho\mu\sigma\nu}$$
$$\frac{\ddot{V}}{V}\bigg|_{\tau=0} = -R_{\mu\nu}\, u^\mu u^\nu$$
$$R = g^{\mu\nu} R_{\mu\nu} = R^\mu_{\ \mu}$$
$$G_{\mu\nu} = R_{\mu\nu} - \frac{1}{2}\, g_{\mu\nu}\, R$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
