Named tensor notation in LaTeX

This style file provides macros for named tensor notation. Please see the paper Named Tensor Notation for background on this notation.

To use the style file, put

\usepackage{namedtensor}

into the preamble of your LaTeX source file (after \documentclass{article} but before \begin{document}).

We write axis names in sans-serif font. To make this easier, \name{axis} prints the axis name "axis", and \ndef{\ax}{axis} defines a macro \ax that prints the axis name "axis".

Binary operators

• Use A \ndot{\ax} B for contractions. You can use \\ to stack up several names.

• You can use \nbin to make new binary operators. For example, Anbin{ax}{star} B gives you a star operator with "axis" writtenunder it.

Functions

• Use \nsum{\ax} A for summation over a named axis.

• You can use \nfun to make new functions. For example, \nfun{\ax}{qux} A defines a function "qux" with "axis" written under it.
