How to Write Upsilon Symbol (υ) in LaTeX

In LaTeX, you can write the upsilon symbol using the \upsilon command for the lowercase upsilon (υ) and the \Upsilon command for the uppercase upsilon (Υ).

The following examples show how to write the upsilon symbol in LaTeX.

How to Write the Upsilon Symbol in Text

We can use the \upsilon command to write the lowercase upsilon symbol in LaTeX document for text.

Suppose we want to write the upsilon symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

This is an example of using the upsilon symbol \(\upsilon\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the upsilon symbol υ in a sentence.

In this example, we use the \upsilon command to display the lowercase upsilon symbol in the text.

How to Write the Upsilon Symbol in Mathematical Expressions

For mathematical expressions, we can use the \upsilon command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the upsilon symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( \alpha + \beta = \upsilon \).

A displayed mathematical expression:
\[
\alpha^2 + \beta^2 = \upsilon^2
\]

\end{document}

Output: 👇️

In this example, we use the \upsilon command to denote the upsilon symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \upsilon command for both text and mathematical expressions. This ensures that the upsilon symbol is properly formatted and displayed in LaTeX document.
