I'm new to Latex and I'm supposed to write a journal paper using the template provided by the journal itself. The guides in the template suggest using PostScript fonts by the package "mathptmx".

  1. I can't produce uppercase Greek letters in math formulas, I tried "\upOmega" (got from http://tug.ctan.org/macros/latex/required/psnfss/psnfss2e.pdf) but it gives a simple vertical line "|".
  2. Is it possible to generate script letters when using this package?

Sorry if there are technical errors in my question, I'm just new to Latex and I'm really confused.

Example:

In the preamble: \usepackage{mathptmx}

\begin{equation}
\upOmega+b^2=C^2
\end{equation}

  • Welcome to TeX.SX! \Omega should work. – egreg Feb 17 '16 at 15:46
  • Thanks egreg! No it doesn't! It gives "\" in the formula. – Mehran Feb 17 '16 at 15:50

    Please, add a minimal working example (MWE) that shows the issue. – egreg Feb 17 '16 at 15:50
  • I just noticed that the problem is with the TeXstudio's PDF viewer! I used Adobe Reader and everything is OK! – Mehran Feb 17 '16 at 16:17

    I'm voting to close this question as off-topic because it has turned out, that this is a rendering problem. – Henri Menke Feb 17 '16 at 16:30
