Key Equations

$$\boxed{Z = \int \mathcal{D}\phi \, e^{iS[\phi]}}$$
$$S[\phi] = \int d^4x \, \mathcal{L}(\phi, \partial_\mu\phi)$$
$$S[\phi] = \int d^4x \left[\frac{1}{2}(\partial_\mu\phi)(\partial^\mu\phi) - \frac{1}{2}m^2\phi^2\right]$$
$$S[\phi] = -\frac{1}{2}\int d^4x \, \phi(x)(\Box + m^2)\phi(x)$$

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