[Tex/LaTex] How to fix this amsmath warning about redefining \vec

amsmathincompatibility

I am using the pss(b) template, which starts with,

\documentclass[pss]{wiley2sp} % provides pss two-column style
\usepackage{amsmath}
%\usepackage{bm}              % uncomment these two packages if you
%\usepackage{w-greek}         % need extended greek-letter functionality in math mode

I always got this warning:

Package amsmath Warning: Unable to redefine math accent \vec.

Does anyone know how to fix this problem?

load amsmath first:

\RequirePackage{amsmath}
\documentclass[pss]{wiley2sp} % provides pss two-column style
...

Then amsmath defines the \vec at first and wiley2sp will redefine it.

Have a look at the mattens package. I have written it to "overcome" these problems

\documentclass{article}
\usepackage{mattens} % use [noformat] for non-bold symbols
\usepackage{bm}
\begin{document}
  $\aS[\Dot]{r}_\alpha$

  or some other examples where \TeX\ makes a real mess on its own

  $\bS[\Dot]{f}^i_j$
\end{document}

[Tex/LaTex] Why does amsmath print a warning about a foreign command

\atopwithdelims is a TeX math primitive command. If you use amsmath, you don't need \atopwithdelims or \atop, use amsmath macros such as \frac, \binom, \genfrac etc. instead.

If a class or package uses this command, or a command such as \choose which uses it, you would get this warning. I would ignore the warning then, otherwise I would have to redefine the concerned macros of the package or class.

Alternatively, I suggest that you use \binom{a}{n}.
