I am writing my dissertation (the document class is report if that makes any difference) and would like to repeat two conjectures which I state in the introduction in a later chapter. The conjecture environment I currently have is:

\newtheorem{conjecture}[theorem]{Conjecture}

and my conjecture looks like this:

\begin{conjecture}\label{r paths}
At most $r$ disjoint monochromatic paths are needed to cover the vertices of any r-edge-coloured $K_n$.
\end{conjecture}

Edit: Sorry for not being clearer, I would like the conjecture to have the same number both times in my document.

Use this code in your preamble:

\usepackage{thmtools, thm-restate}
\newtheorem{conjecture}[theorem]{Conjecture}

and in the body of your document:

\begin{restatable}{conjecture}{PathsConj}\label{r paths}
At most $r$ disjoint monochromatic paths are needed to cover the vertices of any r-edge-coloured $K_n$.
\end{restatable}

where you state the conjecture, and 

\PathsConj*

at the place where you want to restate it.

As you can see, it works somewhat like the empheq environment for amsmath environments: you use a restatable environment, with two mandatory arguments: the name of the theorem-like environment, and the name of the command which will be used to restate the environment. If the environment uses the optional argument (e.g. Conjecture of My Self), it must be given as an optional argument of the restatable environment.

  • Thank you, although this seems to give me different numbers for the two conjectures. Is there any way to prevent this? – JRyan Aug 31 '16 at 15:00
  • I don't understand very well: do you mean you want to repeat two conjectures, or just one, and the number of the repeated conjecture is not the same as the number of the original conjecture? – Bernard Aug 31 '16 at 15:42
  • I want to repeat just one conjecture, and I want the both copies of the conjecture to have the same number. Thanks! – JRyan Aug 31 '16 at 17:40
  • But that's what it does! You must have something else in your code. Could you post an example? – Bernard Aug 31 '16 at 17:58
  • What should I post? I have copied your code exactly and the first copy of the conjecture (in the introduction) has number 1 and the second copy has number 85 :/ – JRyan Sep 03 '16 at 15:49
