I'm trying to write an inverse tensor with mixed indices, meaning I want both a {-1} and a {\lambda} in the superscript - but ideally not at the same level/size, since they are different notations. Double superscripts aren't allowed, so I tried writing

\tensor{\Lambda^{-1}}{^\lambda_\mu} 

using the tensor package, but this wasn't allowed either. Any suggestions for how to get round this?

  • What exactly keeps you from doing \tensor{\Lambda^{-1^{\lambda_\mu}}} (untested)?

  • It shows: Error: Sub/Superscript items out of order... I don't know how to get around double superscripts not being allowed. Mar 16, 2017 at 14:55

    Sounds like a problem due to tensor. If you could post a complete, minimal example, we might be able to help more. Otherwise try the superscript outside of tensor, \tensor{\Lambda}^{-1^{\lambda_mu}}. The usual math mode can handle multiple superscripts.

Just brace the first main argument:

\documentclass{article}
\usepackage{tensor}

\begin{document}

$\tensor{{\Lambda^{-1}}}{^\lambda_\mu}$

\end{document}
