List of LaTeX symbols

LaTeX symbols have either names (denoted by backslash) or special characters. They are organized into seven classes based on their role in a mathematical expression. This is not a comprehensive list. Refer to the external references at the end of this article for more information.

Class 0 (Ord) symbols: Simple / ordinary ("noun")

Latin letters and Arabic numerals

Letters are rendered in italic font; numbers are upright / roman. \imath and \jmath make "dotless" i and j, which are useful in conjunction with hats and accents.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z	$A B C D E F G H I J K L M N O P Q R S T U V W X Y Z$
a b c d e f g h i j k l m n o p q r s t u v w x y z	$a b c d e f g h i j k l m n o p q r s t u v w x y z$

\imath \quad \jmath \quad \hat{\jmath}	$\imath \quad \jmath \quad \hat{\jmath}$

Greek letters

Lower case Greek letters are rendered in italic font; upper case Greek letters are rendered in upright/Roman.

There is also a command \& which is not supported by Wikia's LaTeX parser.

Hats, bars, and accents

Symbols that go above, below, or in the corners of other symbols.

Note 1: dotless i and j (symbols \imath and \jmath) can be used to leave room for whatever hat you want them to wear.

Note 2: \sideset takes two required parameters, left side and right side, and must be followed by a sum class math operator that normally takes subscripts and superscripts below and above the symbol.

The following commands are not supported by the Wikia's LaTeX parser:

\dddot \widetilde \underleftarrow \underrightarrow \underleftrightarrow

Fonts

Bold face: \boldsymbol and \mathbf make bold face symbols, and \pmb makes very bold face symbols. However, \mathbf cannot be applied to Greek symbols, for instance. The AMS "short guide" (see references) contains a cryptic comment, "generally speaking, it is ill-advised to apply \boldsymbol to more than one symbol at a time." Best not to discover why!

LaTeX markup...	...results in:
A_\infty + \pi A_0	$A_\infty + \pi A_0$
\mathbf{A}_\mathbf{\infty} \mathbf{+} \mathbf{\pi} \mathbf{A}_\mathbf{0}	$\mathbf{A}_\mathbf{\infty} \mathbf{+} \mathbf{\pi} \mathbf{A}_\mathbf{0}$
\mathbf{A}_{\boldsymbol{\infty} } \boldsymbol{+} \boldsymbol{\pi} \mathbf{A}_{\boldsymbol{0} }	$\mathbf{A}_{\boldsymbol{\infty} } \boldsymbol{+} \boldsymbol{\pi} \mathbf{A}_{\boldsymbol{0} }$
2\alpha x^2yz+5	$2\alpha x^2yz+5$
\mathbf{2\alpha x^2yz+5}	$\mathbf{2\alpha x^2yz+5}$

The \pmb command is not supported by the Wikia's LaTeX parser.

Spaces

Edit

Main article: Spaces

Simple symbols (class 0) are rendered without any space between them. Operators (class 1) are rendered with spaces. Spacing symbols change the amount of spacing, either by adding more space or taking spaces away. Space is measured in math units, or mu. 18mu equals 1em.

NOTE: commands \thinspace, \medspace, \thickspace, \negthinspace, \negmedspace, \negthickspace, \mspace, and \: are not impemented here at wikia.org!

LaTeX markup...	...results in:	...is used for:
a b c d	$abcd$	Simple symbols (class 0) have no spaces around them
\sin b \cos d	$\sin b \cos d$	Operators (class 1) have thin spaces around them
a \, b \mspace{3mu} c \thinspace d	$a \, b \, c \, d$	thin 3mu space
a \: b \mspace{4mu} c \medspace d	$not\ implemented$	medium 4mu space
a \; b \mspace{5mu} c \thickspace d	$a \; b \; c\; d$	thick 5mu space
a \ b \ c \ d	$a \ b \ c \ d$	thicker 6mu space provided by backslash followed by blank
a \quad b \mspace{18mu} c \quad d	$a \quad b \quad c \quad d$	18mu or 1em space
a \qquad b \mspace{36mu} c \qquad d	$a \qquad b \qquad c \qquad d$	36mu or 2em space
a \! b \mspace{-3mu} c \negthinspace d	$a \! b \! c \! d$	negative thin -3mu space. See \int for a suggested use.
a \negmedspace b \mspace{-4mu} c \negmedspace d	$not\ implemented$	negative medium -4mu space
a \negthickspace b \mspace{-5mu} c \negthickspace d	$not\ implemented$	negative thick -5mu space

Spaces of exactly the size of some rendered text can be obtained using the \phantom, command, and its cousins, \hphantom and \vphantom. They are not implemented here at wikia.org!

LaTeX markup...	...results in:	...is used for:
a \phantom{\int XXX} b	$not\ implemented$	space as wide and high as integral and three X’s
a \hphantom{\int XXX} b	$not\ implemented$	space as wide and high as integral and three X’s; height 0
a \hphantom{\int XXX} b	$not\ implemented$	space of width 0, as high as integral and three X’s

Class 1 (Op) symbols: prefix operator (extensible)

Accumulation operators: sum, integral, union, etc.

Main article: Sum-class symbol

These prefix operators accumulate the things they're prefixed to. "Extensible" means they have variable size to accommodate their operands, and their limits can appear below and above the operator.

$\int$  \int $\oint$  \oint $\bigcap$  \bigcap $\bigcup$  \bigcup

$\bigodot$  \bigodot $\bigoplus$  \bigoplus $\bigotimes$  \bigotimes $\bigsqcup$  \bigsqcup

$\biguplus$  \biguplus $\bigvee$  \bigvee $\bigwedge$  \bigwedge $\coprod$  \coprod

$\prod$  \prod $\sum$  \sum

The \smallint command is not supported by the Wikia's LaTeX parser.

Named operators: sin, cos, etc.

If your favorite operator, say, "foo", isn't listed, then you won't be able to use \foo(x) in your LaTeX equation. But don't fret. You can get the same result with \operatorname{foo}(x). If your made-up operator needs displayed limits, as in \lim or \max, then use \operatorname*{foo}, as in the example in the following table.

$\arccos$  \arccos $\arcsin$  \arcsin $\arctan$  \arctan $\arg$  \arg $\cos$  \cos $\cosh$  \cosh $\cot$  \cot $\coth$  \coth $\csc$  \csc $\deg$  \deg

$\sinh$  \sinh $\sup$  \sup $\tan$  \tan $\tanh$  \tanh $\varinjlim$  \varinjlim $\varprojlim$  \varprojlim $\varliminf$  \varliminf $\varlimsup$  \varlimsup $\operatorname{foo}_0^1$  \operatorname{foo}_0^1

The command \operatorname* is not supported by the wikia's LaTeX parser.
