"Hello world! This is a python implementation of the Cantor pairing function and provides two functions, pair and depair. Sometimes you have to encode reversibly two (or more) values onto a single one. "and are compiled to an array of the specified char values with an additional null terminating character (0-valued) code to mark the end of the string. Install $ pip install pairing Usage from pairing import pair, depair pair(22, 33) # 1573 pair(33, 22) # 1562 depair(1573) # (22, 33) depair(1562) # (33, 32) When (not) to use this. We consider the theory of natural integers equipped with the Cantor pairing function and an extra relation or function Xon N. When Xis equal either to multiplication, or coprimeness, or divisibility, or addition or natural ordering, it can be proved that the theory Th(N;C;X) is undecidable. A recursive formula for the n-degree g.C.p.f. In addition to the diagonal arguments, Georg Cantor also developed the Cantor pairing function (mathbb {N} ^ 2 to mathbb {W}, quad c (x, y) = for the n-degree generalized Cantor pairing function (g.C.p.f., for short), that permits to obtain n−tupling functions which have the characteristics to be n-degree polynomials with rational coefficients. The Cantor pairing function C (which does encode n-tuples for a given integer n) is polynomial, whose variables are the coordinates of n-tuples. Syntax []. The typical example of a pairing function that encodes two non-negative integers onto a single non-negative integer (therefore a function ) is the Cantor function, instrumental to the demonstration that, for example, the rational can be mapped onto the integers.. 1. The twist for coding is not to just add the similar terms, but also to apply a natural number pairing function also. For finite sets, Cantor's theorem can be seen to be true by simple enumeration of the number of subsets. In elementary set theory, Cantor's theorem is a fundamental result which states that, for any set, the set of all subsets of (the power set of , denoted by ()) has a strictly greater cardinality than itself. In particular, it is investigated a very compact expression for the n -degree generalized Cantor pairing function (g.C.p.f., for short), that permits to obtain n −tupling functions which have the characteristics to be n -degree polynomials with rational coefficients. In a more pragmatic way, it may be … Georg Cantor. Though it is continuous everywhere and has zero derivative almost everywhere, its value still goes from 0 to 1 as its argument reaches from 0 to 1. Introduction. Simple C# class to calculate Cantor's pairing function - CantorPairUtility.cs. In this paper, some results and generalizations about the Cantor pairing function are given. The type of a string constant is char [].. backslash escapes []. Cantor (1845–1918) was born in St. Petersburg and grew up in Germany. For example, say you had the following results: f(a, b) = c f(b, a) = d Is there a pairing function that would allow for determining that c is sort of the "inverse" of d without de-pairing ... number-theory functions cantor-set He took an early interest in theological arguments about continuity and the infinite, and as a result studied philosophy, mathematics and physics at universities in Zurich, Göttingen and Berlin, though his father encouraged him to pursue engineering.

In mathematics, the Cantor function is an example of a function that is continuous, but not absolutely continuous.It is a notorious counterexample in analysis, because it challenges naive intuitions about continuity, derivative, and measure.
