      Thanks, interesting suggestion! Here is a minimal working example for illustration:

      \documentclass[11pt]{article}
      \renewcommand{\O}[1]{$\mathcal{O}(#1)$}
      \begin{document}
      \O{n}
      \end{document}

      It is very nice, but I would define a new command so that the original meaning of `\O` (which gives us Ø) is not lost. So I would do like this

      \newcommand\bigO[1]{$\mathcal{O}(#1)$}
