# Force printing of parentheses around a single character in math mode [closed]

Although this is not strictly mathematical notation, I would like to denote an object with a calligraphy capital T and subscript non-italic P. I have this:

\newcommand{\timeP}{$\mathcal{T}_\mathsf{P}$}


That works fine, \timeP gives me TP. Now I need a variant where the P is surrounded by parentheses. But this:

\newcommand{\timePVirt}{$\mathcal{T}_{(\mathsf{P})}$}


just produces the same result as above. The desired result is T(P).

Any ideas? A special escape character? My document uses package amsmath.

EDIT

Indeed the commentators are right---the parentheses should be there. It seems the problem is caused by the combination of these imports:

\usepackage{MnSymbol}

% --- Font choice
%     nightmare! leave alone for your own sanity
%     first choice roman is mathptmx - nice!
\usepackage{mathptmx}


The second one mathptmx was in some document later imported through \input of the thesis template I was using, whereas I added MnSymbol directly to the cls file. Now when I reverse their order:

\usepackage{mathptmx}
\usepackage{MnSymbol}


...the parentheses come back. I think I got the meaning of the comment nightmare!.

Your second definition of \timePshould create the desired result. Could you provide a complete (minimal) example that shows the problem? –  Martin May 19 '12 at 20:19
@Martin. We'll very simple: We call this time virtual or prospective performance time, denoted \timeVirt -- with the above definition, the parentheses are just not printed, so there is no visible difference between \timeP and \timePVirt –  Emit Taste May 19 '12 at 20:27
Actually, I get the parenthesis when adding your definition to a minimalistic document. Thus, it would be helpful if you could provide a complete document, not just a part of it. –  Martin May 19 '12 at 20:32
Sorry, that's a huge thesis template from my University :-/ I have a workaround though (posted as answer below) –  Emit Taste May 19 '12 at 20:35
Found the culprit---see edit. –  Emit Taste May 21 '12 at 19:29

The culprit was

\usepackage{MnSymbol}
\usepackage{mathptmx}


when changing to

\usepackage{mathptmx}
\usepackage{MnSymbol}


it's fine.

The trick from this question's answer does it: escape with \textrm:

\newcommand{\timePVirt}{$\mathcal{T}_\mathsf{\textrm{(}P\textrm{)}}$}

\newcommand{\timePVirt}{\$\mathcal{T}_{(\mathsf{P})} will surely work. There's no reason why it shouldn't. –  egreg May 19 '12 at 20:38
Sorry, it doesn't here. I'm having \documentclass[11pt, a4paper, twoside]{uopthesis} with a 400 lines template file, including some two dozen packages (geometry, titlesec, amsmath, setspace, graphicx, fancyhdr, biblatex, makeidx, nomencl, caption, subfig, paralist, fontenc, inputenc, color, rotating, lettrine, hyperref, hypercap, MnSymbol, babel) –  Emit Taste May 19 '12 at 20:45
