I am using Beamer for preparing presentation in Turkish. Frequently, I need the command \citeauthor. I have replaced "and" between the authors into Turkish ("ve") and "et al." too. However, I want to remove (or replace) the comma just before "and" when there are three or more authors but I don't know how to do it.

Below, you will see my output.

What I need is the following. Ladas, Qian, Vlahos ve Yan.

Here is a MWE.

\documentclass[10pt]{beamer}

\usetheme{Warsaw}
\usecolortheme{whale}

\usepackage[backend=bibtex,firstinits=true,maxbibnames=9,maxcitenames=4]{biblatex}
\usepackage{filecontents}

\DefineBibliographyStrings{english}{%
  and = {ve},
}

\begin{filecontents}{\jobname.bib}

@article {MR1103855,
    AUTHOR = {Ladas, G. and Qian, C. and Vlahos, P. N. and Yan, J.},
     TITLE = {Stability of solutions of linear nonautonomous difference equations},
   JOURNAL = {Appl. Anal.},
  FJOURNAL = {Applicable Analysis. An International Journal},
    VOLUME = {41},
      YEAR = {1991},
    NUMBER = {1-4},
     PAGES = {183--191},
}

\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

\begin{frame}

\begin{itemize}
\item What I get: \citeauthor{MR1103855}.
\item What I need: Ladas, Qian, Vlahos ve Yan.
\end{itemize}
\alert{Note that \texttt{{\textbackslash}citeauthor} command gives a comma before {\textquotedblleft}ve{\textquotedblright}.}

\printbibliography

\end{frame}

\end{document}

And please note that 'firstinits' option is deprecated, use 'giveninits' instead.

  • Thank you for the reply. Do you mind telling me which file should I check to modify it?

  • Just put \DefineBibliographyExtras{english}{\let\finalandcomma=\empty} into the preamble of your presentation? Or what exactly is the question?

  • Which file did you check to decide that we should change the variable '\finalandcomma'?

  • @bkarpuz Ah, now I understand. Right now I looked it up in one of my own projects, where I used it. Back than I probably just googled it and most likely found some question on this website.
