Inductive reasoning
All horses are the same color. All horses are the same color is a falsidical paradox that arises from a flawed use of mathematical induction to prove the statement All horses are the same color. [1] There is no actual contradiction, as these arguments have a crucial flaw that makes them incorrect. This example was originally raised by George ...
Bernoulli's inequality. An illustration of Bernoulli's inequality, with the graphs of and shown in red and blue respectively. Here, In mathematics, Bernoulli's inequality (named after Jacob Bernoulli) is an inequality that approximates exponentiations of . It is often employed in real analysis. It has several useful variants: [1]
Structural induction. Structural induction is a proof method that is used in mathematical logic (e.g., in the proof of Łoś' theorem), computer science, graph theory, and some other mathematical fields. It is a generalization of mathematical induction over natural numbers and can be further generalized to arbitrary Noetherian induction.
Solomonoff's theory of inductive inference
For the following proof we apply mathematical induction and only well-known rules of arithmetic. Induction basis: For n = 1 the statement is true with equality. Induction hypothesis: Suppose that the AM–GM statement holds for all choices of n non-negative real numbers. Induction step: Consider n + 1 non-negative real numbers x 1, . . . , x n+1, .
Definitions. Informally, for a first-order formula of arithmetic with one free variable, the induction principle for expresses the validity of mathematical induction over , while the least number principle for asserts that if has a witness, it has a least one. For a formula in two free variables, the bounding principle for states that, for a ...
