Use this tag if your question is about a well-known conjecture or a conjecture of your own.

In mathematics, a conjecture is a conclusion or a proposition based on incomplete information, for which no proof has been found. There are many famous conjectures, some of which have been proved, some disproved, and many others which still remain open (yet to be proved or disproved). A list of some well-known conjectures can be found on Wikipedia.
