# How to put a cite command next to a theorem with square brackets and no parentheses?

In my bachelor thesis, I use a theorem from another author. I have to cite him. When I use

\newtheorem{proposition}{Proposition}[chapter]
\begin{proposition}\textup{\cite[Proposition 4.7]{LPW}}


I get

This is not exactly what I want. As you can see, there is a point behind "Proposition 4.8". I want that point to be behind the last bracket, so that get

I hope I clarified my problem. Thanks for your help!

• Note the additional braces: \begin{proposition}[{\cite[Proposition 4.7]{LPW}}] – egreg Jan 7 '17 at 14:25
• But this gives me ([ quote ]). Can I eliminate the round brackets? – Lennart Jan 7 '17 at 14:35
• In your first picture there are parentheses (round brackets). Maybe you want \begin{proposition}[Proposition 4.7 in \cite{LPW}]. Or, if you prefer, \begin{proposition}\textup{\cite[Proposition 4.7]{LPW}} – egreg Jan 7 '17 at 14:40
• Thank you egreg! Your last suggestion is almost perfect. Is it possible to put the point behind the quote? Right now I have Proposition 4.8. [Lev09, Proposition 4.7] Can I get Proposition 4.8 [Lev09, Proposition 4.7]. ? – Lennart Jan 7 '17 at 14:50
• i extended the title to be more specific, to show that this is not the same as the suggested "duplicate". – barbara beeton Jan 7 '17 at 15:16
