Although additive combinatorics is a fairly new branch of combinatorics (the term additive combinatorics was coined by Terence Tao and Van H. Vu in their 2006 book of the same name), a much older problem, the Cauchy–Davenport theorem, is one of the most fundamental results in this field.
In mathematics, a recurrence relation is an equation according to which the th term of a sequence of numbers is equal to some combination of the previous terms. Often, only previous terms of the sequence appear in the equation, for a parameter that is independent of ; this number is called the order of the relation.
Primitive recursive arithmetic (PRA) is a quantifier-free formalization of the natural numbers. It was first proposed by Norwegian mathematician Skolem (1923) , [ 1 ] as a formalization of his finitistic conception of the foundations of arithmetic , and it is widely agreed that all reasoning of PRA is finitistic.
[1] [2] Every term of the harmonic series after the first is the harmonic mean of the neighboring terms, so the terms form a harmonic progression; the phrases harmonic mean and harmonic progression likewise derive from music. [2] Beyond music, harmonic sequences have also had a certain popularity with architects.
An ω-model is a model for a fragment of second-order arithmetic whose first-order part is the standard model of Peano arithmetic, [1] but whose second-order part may be non-standard. More precisely, an ω-model is given by a choice S ⊆ P ( ω ) {\displaystyle S\subseteq {\mathcal {P}}(\omega )} of subsets of ω {\displaystyle \omega } .
A related question is, as people enter a room one at a time, which one is most likely to be the first to have the same birthday as someone already in the room? That is, for what n is p(n) − p(n − 1) maximum? The answer is 20—if there is a prize for first match, the best position in line is 20th. [citation needed]
The sequence produced by other choices of c can be written as a simple function of the sequence when c=1. [1]: 11 Specifically, if Y is the prototypical sequence defined by Y 0 = 0 and Y n+1 = aY n + 1 mod m, then a general sequence X n+1 = aX n + c mod m can be written as an affine function of Y:
The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
