希腊字母｜Greek Letters
| 渲染 | 输入 | 渲染 | 输入 |
|---|---|---|---|
\alpha, A | \nu, N | ||
\beta, B | \xi, \Xi | ||
\gamma, \Gamma | o, O | ||
\delta, \Delta | \pi, \Pi | ||
\epsilon, \varepsilon, E | \rho, \varrho, P | ||
\zeta, Z | \sigma, \Sigma | ||
\eta, H | \tau, T | ||
\theta, \vartheta, \Theta | \upsilon, \Upsilon | ||
\iota, I | \phi, \varphi, \Phi | ||
\kappa, K | \chi, X | ||
\lambda, \Lambda | \psi, \Psi | ||
\mu, M | \omega, \Omega |
值得注意的是，epsilon、theta、rho 以及 phi 四个字母拥有三种变体，而其它的（/大多数）字母仅拥有两种变体，即大写（Upper）与小写（Small）。
关于此现象的更多讨论，请阅读 LaTeX 中的 \epsilon 与 \varepsilon。
