# Cantor continuum hypothesis

Chief among the holes is the continuum hypothesis, a 140-year-old statement about the possible sizes of infinity as incomprehensible as it may seem, endlessness comes in many measures: for example, there are more points on the number line, collectively called the “continuum,” than there are counting numbers. The continuum hypothesis cesare brazza history of mathematics rutgers, spring 2000 infinity is up on trial (bob dylan, visions of johanna, cited in in the light of logic), pg 28these five words suffice to summarize the essence of cantor's work. Cantor spent years unsuccessfully trying to prove his continuum hypothesis, that the cardinality of the geometric continuum is the smallest uncountable cardinal number, that is, p(aleph-null) = aleph-one in 1936 g–del showed that cantor s continuum hypothesis was at least consistent with set theory, and in 1963 paul cohen showed it was in. Georg cantor's conjecture, the continuum hypothesis without equations, this states that for any set of real numbers, s, one of three things happen: s is finite s has a 1-1 correspondence to the integers s has a 1-1 correspondence to the reals there is nothing in between the integers and reals.

The continuum hypothesis this is one half of a two-part article telling a story of two mathematical problems and two men: georg cantor, who discovered the strange world that these problems inhabit, and paul cohen (who died last year), who eventually solved them. The continuum hypothesis is a statement ﬁrst formulated by george cantor regarding the sizes of inﬁnite sets cantor had shown that the set of natural numbers n was smaller than the set of real number r using the notion of. Find out more about cantor's infinities in the second part of this article the continuum hypothesis by richard elwes you can find out more about gödel's incompleteness theorems in the plus article gödel and the limits of logic by john w dawson.

Cantor’s continuum hypothesis is a statement regarding sizes of infinity to see how infinity can have more than one size, let’s first ask ourselves how the sizes of ordinary numbers are compared. The continuum hypothesis (which has been shown to be neither provable nor disprovable, but for the purposes of this question let us assume that it is true) claims that there are no sets with a cardinality between that of integers and the real numbers. This is the continuum hypothesis without getting into it too deeply, the basic idea is this, we have a number line, that runs to infinity in either direction 1234 etc. Cantor called the hypothesis c =ℵ 1 the continuum hypothesiscontinuum hypothesiscontinuum hypothesis and went to his death not resolving the question a proof of the continuum hypothesis would confirm that the continuum c is the smallest uncountable set and would bridge the gap between the countable.

The hypothesis, due to g cantor (1878), stating that every infinite subset of the continuum $\mathbf{r}$ is either equivalent to the set of natural numbers or to $\mathbf{r}$ itself. The generalized continuum hypothesis is a much stronger statement involving the initial sequence of transfinite cardinal numbers, and is also independent of zfc in terms of the arithmetic of cardinal numbers (as introduced by cantor) the continuum hypothesis reads. Consistency of the continuum hypothesis bruce w rogers april 22, 2005 1 introduction one of the basic results in set theory is that the cardinality of the power set of the natural numbers is the same as the cardinality of the real numbers, which so cantor hypothesized that 2. Cantor’s continuum hypothesis:suppose that x for the problem of the continuum hypothesis, i shall focus on one specific approach which has de-veloped over the last few years this should not be misinterpreted as a claim that this is the only approach or even that it is the best approach how. His 1940 book, better known by its short title, the consistency of the continuum hypothesis, is a classic of modern mathematics the continuum hypothesis, introduced by mathematician george cantor in 1877, states that there is no set of numbers between the integers and real numbers.

## Cantor continuum hypothesis

Also, the continuum hypothesis (ch) has nothing to do with cantor’s diagonalization argument mark and germain mention the ch because if germain proof were right, the ch would describe a world. Cantor and generalized contunuum hypotheses are shown to be possibly factually false two new hyper-continuum hypotheses are posted to challenge pure mathematics and stir investigations of the abstract multispatial hyperspace. This is cantor’s continuum hypothesis but, although cantor’s set theory has now had a development of more than sixty years and the [continuum] problem is evidently of great importance for it, nothing has been. Thecontinuumhypothesis peter koellner september 12, 2011 the continuum hypotheses (ch) is one of the most central open problems in set theory, one that is important for both mathematical and philosophical reasons cantor’s famous continuum hypothesis (ch) is the.

- A side note: in fluid mechanics the continuum hypothesis is the assertion that a fluid which is really a collection of interacting molecules can be treated as a continuum it's not really a hypothesis.
- Cantor's theorem implies that there are infinitely many infinite cardinal numbers, and that there is no largest cardinal number it also has the following interesting consequence: there is no such thing as the set of all sets'.

Cantor's continuum hypothesis is perhaps the most famous example of a mathematical statement that turned out to be independent of the zermelo-fraenkel axioms what is less well known is that the continuum hypothesis is a useful tool for solving certain sorts of problems in analysis. I examine various claims to the effect that cantor's continuum hypothesis and other problems of higher set theory are ill-posed questions the analysis takes into account the viability of the underlying philosophical views and recent mathematical developments. His 1940 book, better known by its short title,the consistency of the continuum hypothesis, is a classic of modern mathematics the continuum hypothesis, introduced by mathematician george cantor in 1877, states that there is no set of numbers between the integers and real numbers.
