[Tex/LaTex] How to change the spacing for math operators

math-modemath-operatorsspacing

I have defined my own math operator (for displaying the order of certain function sequences–this is not the "normal" Big-O notation, though) by:

\newcommand{\order}[1]{\ensuremath{\operatorname{o}\left({#1}\right)}}

This leads to pretty strange spacing:

How can I resolve this? Is there a better way to specify the operator?

First, I think in general it is probably a better idea to use \DeclareMathOperator rather than a combination of \newcommand and \operatorname. That said, I think your problem is because you used \left(. It should be fixed if you insert \mathopen{} before the \left(. See also Difference between \big[ and \bigl[

[Tex/LaTex] Problem with \specialcomment-command and equation/align-environments

This isn't actually caused by the comment package, it's the colour change, as you can see from this example.

\documentclass{article}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{xcolor}
\begin{document}
\begin{equation}
x=y
\end{equation}

\blindtext

\color{red}
\begin{equation}
x=y
\end{equation}
\color{black}

%
\blindtext

\color{red}
Just some normal text, no problem there.
\color{black}

\blindtext
\end{document}

To eliminate the problem with blank lines, replace \color{black} with \vskip0pt\color{black}\noindent. However, the colouring macros will still cause trouble if a mycomment2 is followed by an environment that begins a new line, and I am not aware of any general solution. @David Carlisle gives a good explanation of the problem and a workaround here.
