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") [edit | edit source]

Latin letters and Arabic numerals [edit | edit source]

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

Greek letters [edit | edit source]

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

Other alphabetic characters [edit | edit source]

Other simple symbols [edit | edit source]

The following characters don't have any spacing associated with them. That is, they are simple symbols, in class 0.

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

Hats, bars, and accents [edit | edit source]

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

Grade 1: dotless i other j (symbols and) can be used to leave room for whatever hat you want them to wear.

Note 2: 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 [edit | edit source]

Bold face: and make bold face symbols, and makes very bold face symbols. However, 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!

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

Spaces [edit | edit source]

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!
