A mathematical proof is a deductive argument for a mathematical statement, showing that the stated assumptions logically guarantee the conclusion. The...- possible to find it through a mathematical proof. The weaker form of the theorem can be proved from the undecidability of the halting problem as follows...

of mathematical induction infers that a statement involving a natural number n (that is, an integer n ≥ 0 or 1) holds for all values of n. The proof consists...- complicated mathematical structures. Some of the most important proofs of impossibility found in the 20th century were those related to undecidability, which...
In mathematics, a proof without words (or visual proof) is an illustration of an identity or mathematical statement which can be demonstrated as self-evident...- Mathematical logic is the study of formal logic within mathematics.

Conjecture (redirect from Undecidable conjectures)In mathematics, a conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof. Some conjectures, such as the Riemann...- Axiom (redirect from Mathematical assumption)to axiomatize a given mathematical domain.
