Key Equations

$$\mathcal{L} = \frac{1}{2}\partial_\mu \phi \partial^\mu \phi - V(\phi)$$
$$Q = \frac{1}{2v}\int_{-\infty}^{\infty} dx \, \partial_x \phi = \frac{1}{2v}[\phi(\infty) - \phi(-\infty)]$$
$$\mathcal{L} = -\frac{1}{4}F_{\mu\nu}^a F^{a,\mu\nu} + \frac{1}{2}(D_\mu \phi)^a(D^\mu \phi)^a - V(\phi)$$
$$V(\phi) = \frac{\lambda}{4}(\phi^2 - v^2)^2$$

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