# How can I remove author and co-authors from a navigation bar in beamer presentation?

There are 6 co-authors of my presentation. How can I remove all their names from the navigation bar and leave them on the title page? Thanks for your help

Which beamer theme are you using? You can try a different beamer theme that does not contain the author names in the navigation bar. –  ShreevatsaR May 11 '11 at 9:32
I am using PaloAlto. The answer below is working fine, but thanks anyway for a suggestion. –  Marcin May 11 '11 at 9:46

Probably specifying the optional short author list will do the trick:

\author[First Author]{First Author \and Second Author \and Third Author}


Edit: As discussed below, the suggested solution works for my setup and I would guess that it does so for most setups. More specifically, it works if the theme (or you yourself manually) uses \insertshortauthor to display the author list in the navigation bar (header, footer, etc.). The same goes for \insertshorttitle and \insertshortdate..

I'll vote you up once you test it. :-) –  Matthew Leingang May 11 '11 at 9:38
I tested it and it does work:) –  Marcin May 11 '11 at 9:45
Well, it works for my setup. I don't know if it will for Marcin's theme etc., but I would guess so. Hence the "probably" :-) It works if the theme (or you yourself manually) uses \insertshortauthor to display the author list in the navigation bar (header, footer, etc.). The same goes for \insertshorttitle and \insertshortdate.. –  janitor048 May 11 '11 at 9:46
That comment would make a great edit to your answer, whereas "probably" makes it sound like you just typed it in without testing. (but you did already get my up vote; halo effect from the green check) –  Matthew Leingang May 11 '11 at 10:54
@Matthew: I've amended my answer.. Sorry for being a bit vague. –  janitor048 May 12 '11 at 20:34
