  1. Theorem

    In mathematics, a theorem is a statement that has been proven on the basis of previously established statements, such as other theorems, and previously accepted statements, such as axioms. The proof of a mathematical theorem is a logical argument demonstrating that the conclusion is a necessary consequence of the hypotheses. This argument is in accord with the rules of a deductive system. The proof of a theorem is often interpreted as justification of the truth of the conclusion, but different deductive systems could be interpreted differently, depending on the meanings assigned to the derivation rules. Given such an interpretation of proof as justification of truth, the conclusion is viewed as true in the case that the hypotheses are true, without any further assumptions. In this light, the concept of a theorem is fundamentally deductive, in contrast to the notion of a scientific theory, which is empirical. Although they can be written in a completely symbolic form using, for example, propositional calculus, theorems are often expressed in a natural language such as English. The same is true of proofs, which are often expressed as logically organized and clearly worded informal arguments, intended to convince readers of the truth of the statement of the theorem beyond any doubt, and from which arguments a formal symbolic proof can in principle be constructed. Such arguments are typically easier to check than purely symbolic ones—indeed, many mathematicians would express a preference for a proof that not only demonstrates the validity of a theorem, but also explains in some way why it is obviously true. In some cases, a picture alone may be sufficient to prove a theorem. Because theorems lie at the core of mathematics, they are also central to its aesthetics. Theorems are often described as being "trivial", or "difficult", or "deep", or even "beautiful". These subjective judgments vary not only from person to person, but also with time: for example, as a proof is simplified or better understood, a theorem that was once difficult may become trivial. On the other hand, a deep theorem may be simply stated, but its proof may involve surprising and subtle connections between disparate areas of mathematics. Fermat's Last Theorem is a particularly well-known example of such a theorem.

Examples of theorem in a Sentence

  1. David Eisenbud:

    The legend around this chalk is that it's impossible to write a false theorem using the chalk, but I think I've disproved that many times.

  2. Henri Poincare:

    Thus, be it understood, to demonstrate a theorem, it is neither necessary nor even advantageous to know what it means....[A] machine might be imagined where the assumptions were put in at one end, while the theorems came out at the other, like the legendary Chicago machine where the pigs go in alive and come out transformed into hams and sausages. No more than these machines need the mathematician know what he does.

  3. E. Kim Nebeuts:

    To state a theorem and then to show examples is literally to teach backwards.
