I don't follow this. In my mind a theorem consists of a statement of the theorem followed by a proof of its truth. See, for example, the theorems in [[ElementaryGroupTheory]]



One may seek to prove a new theorem by hypothesis->investigation->conclusion, but that isn't the theorem.

Mathematicians, logicians, and others who prove [[theorem]s seek to establish chains of reasoning that are convincing to others.


There are many ways of proving a theorem correct, including:

  • Reductio ad absurdum: If we can show that the assumption that our hypothesis is false leads to a contradiction, it follows that the hypothesis must be true.
