I am using the \listtheorems command from ntheorem to generate a list of theorems for a document. However, because I number the theorems inside sections, the theorem number is a bit on the long side, and when typeset the theorem numbers run into the theorem name.

I know that for lists of figures or the TOC I can control this using tocloft and setting numwidth, is there something similar I can do for the theorem lists generated by ntheorem?



\begin{Theorem}[False Theorem]
This is not a theorem

List of theorems:

The output looks like:

Colliding text

Here's the tail end of the log from latex building the MWE:

** Generating table of Theorem
Overfull \hbox (12.5556pt too wide) detected at line 1
\OT1/cmr/m/n/10 11.22.34 

\openout3 = `listthm.thm'.


] (./listthm.aux) ) 
  • A MWE is needed.

Add the following after loading ntheorem:


The usual definition has 2.3em instead of 5em; adjust until you're satisfied.

  • thanks, but unfortunately I hadn't realised that the fix would also depend on the fact that I am using hyperref. In any case, a suitable modification to the appropriate lines in ntheorem.sty patches the problem. Feb 2, 2012 at 13:11
  • Yes, the macro is slightly more complicated, but it's sufficient to find its definition in ntheorem.sty and change the 2.3em to the desired value.
