vector arrow with superscript

Question

I want to have a vector with a superscript:

\vec{o}^t

But this gives very bad results: the t is overlapping with the vector arrow. How do I fix this (and why does this give bad results in the first place) ?

Answer 1

I don't really know why the result is bad; I suspect it has to do with the width of the letter. I wouldn't use such a notation, but that's a personal opinion.

With

\vec{o}^{\,t}

the superscript is moved a bit to the right. One might perhaps let TeX do some computations in order that the shift to the right of the superscript is automatic.

Answer 2

Try this:

\documentclass{article}
\usepackage{esvect}
\begin{document}
$\vv{o}^t \ \vv{o^t}$
$\vec{o}^{\,t}$
\end{document}

(I have included egreg's code to make the comparison easier.)

The first two are done using the esvect package, the third is egreg's code.
