The Continuum Hypothesis
The continuum hypothesis (CH) is one of the most central open problems in set theory, one that is important for both mathematical and philosophical reasons. The problem actually arose with the birth of set theory; indeed, in many respects it stimulated the birth of set theory. In 1874 Cantor had shown that there is a one-to-one correspondence ...
Continuum hypothesis
In mathematics, specifically set theory, the continuum hypothesis (abbreviated CH) is a hypothesis about the possible sizes of infinite sets.It states that there is no set whose cardinality is strictly between that of the integers and the real numbers,. or equivalently, that any subset of the real numbers is finite, is countably infinite, or has the same cardinality as the real numbers.

8.5: The Continuum Hypothesis and The Generalized Continuum Hypothesis
The usual axioms for mathematics are called ZFC; the Zermelo-Frankel set theory axioms together with the axiom of choice. The "ultimate weirdness" we've been describing about the continuum hypothesis is a result due to a gentleman named Paul Cohen that says "CH is independent of ZFC.".
Continuum hypothesis
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. An equivalent formulation (in the presence of the axiom of choice) is: $$ 2^ {\aleph_0} = \aleph_1 $$ (see Aleph ).

The Continuum: History, Mathematics, and Philosophy

Infinity
The Continuum Hypothesis states there is no infinite set with a cardinal number (i.e., cardinality) between that of the infinite set of natural numbers ℵ 0 and the infinite set of real numbers c That is, c = ℵ 1. In 1900, David Hilbert made a list of mathematical problems that he deemed most important to solve in the next century.
Notes to The Continuum Hypothesis
We have of necessity presupposed much in the way of set theory. The reader seeking additional detail—for example, the definitions of regular and singular cardinals and other fundamental notions—is directed to one of the many excellent texts in set theory, for example Jech (2003). 3.
Continuum (set theory)
In the mathematical field of set theory, the continuum means the real numbers, or the corresponding (infinite) cardinal number, denoted by . Georg Cantor proved that the cardinality is larger than the smallest infinity, namely, .He also proved that is equal to , the cardinality of the power set of the natural numbers.. The cardinality of the continuum is the size of the set of real numbers.
PDF Conceptions of the Continuum Solomon Feferman
Abstract: A number of conceptions of the continuum are examined from the perspective of conceptual structuralism, a view of the nature of mathematics according to which mathematics emerges from humanly constructed, intersubjectively established, basic structural conceptions. This puts into question the idea from current set theory that the ...
Can the Continuum Hypothesis Be Solved?
The continuum hypothesis is a problem of a very different kind; we actually can prove that it is impossible to solve it using current methods, which is not a completely unknown phenomenon in mathematics. For example, the age-old trisection problem asks: can we trisect a given angle by using just a ruler and compass?
Independence of the Continuum Hypothesis: an Intuitive Introduction
The independence of the continuum hypothesis is a result of broad impact: it settles a basic question regarding the nature of N and R, two of the most familiar mathematical structures; it introduces the method of forcing that has become the main workhorse of set theory; and it has broad implications on mathematical foundations and on the role of syntax versus semantics. Despite its broad ...
The Continuum Hypothesis, explained
Cantor formulated one possible answer in his famous continuum hypothesis. This is one way to state it: Every infinite set of real numbers is either of the size of the natural numbers or of the size of the real numbers. The continuum hypothesis is, in fact, equivalent to saying that the real numbers have cardinality א1.
Forcing (mathematics)
Forcing (mathematics) In the mathematical discipline of set theory, forcing is a technique for proving consistency and independence results. Intuitively, forcing can be thought of as a technique to expand the set theoretical universe to a larger universe by introducing a new "generic" object . Forcing was first used by Paul Cohen in 1963, to ...
Cardinality of the continuum
The smallest infinite cardinal number is ().The second smallest is ().The continuum hypothesis, which asserts that there are no sets whose cardinality is strictly between and , means that =. The truth or falsity of this hypothesis is undecidable and cannot be proven within the widely used Zermelo-Fraenkel set theory with axiom of choice (ZFC).
Aleph number
Aleph-nought, aleph-zero, or aleph-null, the smallest infinite cardinal number. In mathematics, particularly in set theory, the aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets that can be well-ordered.They were introduced by the mathematician Georg Cantor and are named after the symbol he used to denote them, the Hebrew letter aleph (ℵ).
