GREEK LETTER FORMS
LaTeX Greek letters: uppercase names and variant forms
Examples checked with MathTexLab’s base and AMS math renderer · Display style
Greek mathematical letters have command names, but uppercase and lowercase forms are not always obtained by changing the command’s first letter. Use the Symbols Library to find the available form and inspect its preview.
Respect command case
\gamma and \Gamma are different glyphs. Some
uppercase Greek letters look like Latin letters and are commonly written
with those Latin characters. Do not assume that every lowercase command has
a corresponding capitalized macro. Search the library or supported-command
index when unsure.
Compare variant forms
The pairs below are alternative glyph forms, not automatically different mathematical quantities. Choose a convention for your document and apply it consistently. The reader needs a definition if the distinction carries meaning.
\epsilon\quad\varepsilon\qquad\phi\quad\varphi\qquad\theta\quad\varthetaTerminate command names clearly
A command made of letters continues until a non-letter boundary. To put an
ordinary x after alpha, use \alpha x or \alpha{}x;
\alphax is a different, unknown name. Braces can terminate a
command without printing visible characters.
Copy a complete command
Search by the letter name or a command such as \theta. Copy the
library result, then add subscripts or relations in the Equation Editor. A
glyph is notation, not a translation of your variable definition. User
source and exported formulas are never translated when the site language
changes.
Syntax reference
