I would like to have a unique font (Times New Roman or an equivalent one) for both text and equations.

I'm actually using the commands below, which work only for text mode:


example:enter image description here


% Document
example text mode: 12345

$example \ math \ mode: 12345$

The psd_thesis.cls is reported below:





\renewcommand{\baselinestretch}{1.5}  % Double-spaced

\usepackage[round]{natbib}  % bib style

\usepackage[tx]{sfmath}      % a package of fonts
\usepackage{helvet}             % For Helvetica (Arial is just a bad copy of Helvetica)

\vspace*{50\p@}%  {\parindent \z@ \raggedright \normalfont
\ifnum \c@secnumdepth >\m@ne
    \large \scshape \bfseries \@chapapp\space \thechapter
    \vskip 20\p@
\large \bfseries #1\par\nobreak
\vskip 40\p@  }}

\vspace*{50\p@}%{\parindent \z@ \raggedright
\large \scshape \bfseries  #1\par\nobreak
\vskip 40\p@  }}  

\renewcommand{\section}{\@startsection{section}% % the name{1}% % the level{0mm}% % the indent{3.0\baselineskip}% % the before skip{2.5\baselineskip}% % the after skip{\normalfont \normalsize}} % the style

\renewcommand{\subsection}{\@startsection{subsection}% % the name
{2}% % the level{0mm}% % the indent{-\baselineskip}% % the before skip{1.5\baselineskip}% % the after skip{\normalfont \normalsize}} % the style

    You do get Times for math letters, unless you follow that\usepackage call with some other font selection. A minimal example is needed. – egreg Jul 4 '16 at 8:15
  • Now it's clearer: the fault is apparently on psd_thesis.cls, but a pointer to it is needed. – egreg Jul 4 '16 at 9:00

    Remove \usepackage[tx]{sfmath} or, possibly, don't use the class at all. – egreg Jul 4 '16 at 9:24

As far as I can see, the class is meant to typeset everything in a sans serif font. So, if you have to use it, don't try changing its settings.

If you are not required to use the class, just avoid it: its typographic decisions are funny, for example the enormous distance between a section title and the following text (twice and a half the baselineskip, with double spacing, means 1.85cm below; it's 2.2cm above).

Anyway, the part of the class that sets everything to sans serif is

\usepackage[tx]{sfmath}      % a package of fonts
\usepackage{helvet}             % For Helvetica (Arial is just a bad copy of Helvetica)

Comment it and you'll be free to choose whatever font you like.

  • I followed your suggestion but in math mode I got cursive Times New Roman for letters and a different style for numbers: [![enter image description here][1]][1] [1]: i.stack.imgur.com/jAwY0.jpg I would like that numbers appear in the same style as the letters. Thank you – Luca Jul 4 '16 at 13:30
  • @Luca I don't understand: it is traditional to have letters in math mode printed in italic shape and numbers upright. – egreg Jul 4 '16 at 13:56
