### TeX problem

In the middle of this entry, I have the code:

\begin{proof}[Proof of theorem 1]

According to the PM Content and Style Guide, this is supposed to make "Proof of theorem 1." appear italicized, which is what I want. Instead, what is appearing is "Proof." italicized, then "[Proof of theorem 1]". How do I fix this?

### Re: TeX problem

It looks ok in page images mode, so maybe it's a PM problem. Perhaps rerendering might help.

### Re: TeX problem

Rerendering doesn't help, but it looks the way that I want it to in page images mode. Hmmm....

### Re: TeX problem

I forced the "Proof of theorem 1" to appear the way that I want it to, but now, in html mode only, there's some gibberish that appears just before the bibliography. Any ideas on how to fix this?

### Re: TeX problem

I don't know, but you might try removing the empty line between the last line of your proof and \end{proof}. At least this would mean the square would appear in the right place, and it might even do something to the weird text.

### Re: TeX problem

It put the square in the right spot (I didn't even notice that!), but the weird text is still there. :-( Any other advice?

### Eureka! QED

I finally figured it out! Since I made the "Proof of theorem 1" outside of the proof environment, I had put a \qed at the end of the proof. In order to avoid the "ARRAY&$!*#" stuff, I had to put \qed in math mode. In any case, I'm so happy it's fixed now! Thanks silverfish for giving me suggestions.$\qed\$
