  3. Mathematical proof - Wikipedia

    en.wikipedia.org/wiki/Mathematical_proof

    An elementary proof is a proof which only uses basic techniques. More specifically, the term is used in number theory to refer to proofs that make no use of complex analysis . For some time it was thought that certain theorems, like the prime number theorem , could only be proved using "higher" mathematics.

  4. List of long mathematical proofs - Wikipedia

    en.wikipedia.org/wiki/List_of_long_mathematical...

    This is a list of unusually long mathematical proofs. Such proofs often use computational proof methods and may be considered non-surveyable. As of 2011, the longest mathematical proof, measured by number of published journal pages, is the classification of finite simple groups with well over 10000 pages. There are several proofs that would be ...

  5. Category:Mathematical proofs - Wikipedia

    en.wikipedia.org/wiki/Category:Mathematical_proofs

    This category includes articles on basic topics related to mathematical proofs, including terminology and proof techniques.. Related categories: Pages which contain only proofs (of claims made in other articles) should be placed in the subcategory Category:Article proofs.

  6. Proof (truth) - Wikipedia

    The subject of logic, in particular proof theory, formalizes and studies the notion of formal proof. [8] In some areas of epistemology and theology, the notion of justification plays approximately the role of proof, [9] while in jurisprudence the corresponding term is evidence, [10] with "burden of proof" as a concept common to both philosophy ...

    The proof that follows is inspired by Euclid's original version of the Euclidean algorithm. Assume that is the smallest positive integer which is the product of prime numbers in two different ways. Incidentally, this implies that , if it exists, must be a composite number greater than . Now, say

  9. Mathematical fallacy - Wikipedia

    en.wikipedia.org/wiki/Mathematical_fallacy

    In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept called mathematical fallacy.There is a distinction between a simple mistake and a mathematical fallacy in a proof, in that a mistake in a proof leads to an invalid proof while in the best-known examples of mathematical fallacies there is some element of concealment or ...
