Northeast Arrow in LaTeX (\nearrow)

Where it is used

Draws a diagonal arrow pointing up and to the right, for increasing trends and diagram edges.

\nearrow is often used informally for "increases to", as in a_n \nearrow a, the diagonal counterpart of \uparrow. It also connects entries in hand-built diagrams, matrix illustrations, and Hasse-style sketches. With \searrow, \swarrow, and \nwarrow it forms a full set of diagonal arrows. These do not stretch, so for long diagonal arrows a diagram tool is a better fit. In economics and data-analysis notes it can summarize a rising trend in a table cell. Define the meaning once, since it is notation rather than a formal symbol.

Minimal compilable example

Paste this into an empty .tex file and compile it with pdfLaTeX, XeLaTeX or LuaLaTeX.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
Northeast Arrow: $\nearrow$

\[ a_n \nearrow a \implies \sup_n a_n = a \]
\end{document}

Frequently asked questions

How do I write Northeast Arrow in LaTeX?

Type \nearrow in math mode, for example $a_n \nearrow a \implies \sup_n a_n = a$. It works in plain LaTeX without loading any package.

Which package do I need for \nearrow?

None. \nearrow is part of standard LaTeX, so it compiles with nothing in the preamble but the document class.

Can I use \nearrow in text mode, or only in math mode?

Only in math mode. Outside $...$ LaTeX stops with "Missing $ inserted", so write $\nearrow$ in running text. If you only need the glyph in text, paste the Unicode character ↗ instead (with XeLaTeX or LuaLaTeX and a font that has it).
