In mathematics, the Cantor set is a set of points lying on a single line segment that has a number of remarkable and deep properties.

Given a trigonometric series f ( x ) with S as its set of zeros, Cantor had discovered a procedure that produced another trigonometric series that had S ' as its set of zeros, where S ' is the set of limit points of S. If p ( 1 ) is the set of limit points of S, then he could construct a trigonometric series whose zeros are p ( 1 ).

By considering only the points of the tori that are not removed at some stage, an embedding results of the sphere with a Cantor set removed.

This embedding extends to the whole sphere, since points approaching two different points of the Cantor set will be at least a fixed distance apart in the construction.

In mathematics, the Smith – Volterra – Cantor set ( SVC ), fat Cantor set, or ε-Cantor set is an example of a set of points on the real line R that is nowhere dense ( in particular it contains no intervals ), yet has positive measure.

Continuing indefinitely with this removal, the Smith – Volterra – Cantor set is then the set of points that are never removed.

Thus there are points where V ′ takes values 1 and − 1 in every neighborhood of each of the endpoints of intervals removed in the construction of the Smith – Volterra – Cantor set S. In fact, V ′ is discontinuous at every point of S, even though V itself is differentiable at every point of S, with derivative 0.

One of the greatest achievements of Georg Cantor was the construction of a one-to-one correspondence between the points of a square and the points of one of its edges by means of continued fractions.

More abstractly, a natural class of objects to study in topology are objects that are homogeneous ( all points are topologically the same: the group of self-homeomorphisms acts transitively ) and " finite type " or " tame " ( to rule out spaces such as the Cantor set, where each open set contains uncountably many connected components ); more generally, a space of " finite type " where the self-homeomorphism group has finitely many orbits, forming the strata.

Headquartered in Midtown Manhattan, New York City, Cantor Fitzgerald was formerly based in the World Trade Center and was the company hardest hit by the September 11, 2001 attacks, which killed all 658 of its employees who were in the office at the time ( out of 960 who were based there ).

( Konig is now remembered as having only pointed out that some sets cannot be well-ordered, in disagreement with Cantor.

Dedekind, whom Cantor befriended in 1872, cited this paper later that year, in the paper where he first set out his celebrated definition of real numbers by Dedekind cuts.

In Waguespack and Cantor ( 1996 ), the authors point out that JIT would require a significant change in the supplier / refiner relationship, but the changes in inventories in the oil industry exhibit none of those tendencies.

The Hollywood Stock Exchange, a virtual market game established in 1996 and now a division of Cantor Fitzgerald, LP, in which players buy and sell prediction shares of movies, actors, directors, and film-related options, correctly predicted 32 of 2006's 39 big-category Oscar nominees and 7 out of 8 top category winners.

It is not a true ordering because the trichotomy law need not hold: if both and, it is true by the Cantor – Bernstein – Schroeder theorem that i. e. A and B are equinumerous, but they do not have to be literally equal ; that at least one case holds turns out to be equivalent to the Axiom of choice.

After Marge bails them out, Bart and Homer can speak fluent Japanese, and have fully absorbed, as Cantor writes, the " exclusionary " character of the Japanese culture, as Homer asks Bart ( in Japanese, with English subtitles ): " Should we tell them and Lisa the secret to inner peace?

Cantor comes to the jail to bail them out, but finds there is not a Yussel Rabinovitch there, only a Jess Robin.

Along with him are a few other out of work actors that appear as caricatures of Al Jolson, Jack Benny, Eddie Cantor and Bing Crosby.

Cantor introduced fundamental constructions in set theory, such as the power set of a set A, which is the set of all possible subsets of A.

Cantor established these results using two constructions.

* the various ( but equivalent ) constructions of the real numbers by Dedekind and Cantor resulting in the modern axiomatic definition of the real number field ;

A generalized form of the diagonal argument was used by Cantor to prove Cantor's theorem: for every set S the power set of S, i. e., the set of all subsets of S ( here written as P ( S )), is larger than S itself.

Cantor himself only mentioned the ternary construction in passing, as an example of a more general idea, that of a perfect set that is nowhere dense.

Cantor Fitzgerald lost over two-thirds of its workforce, considerably more than any of the other World Trade Center tenants or the New York City Police Department and New York City Fire Department.

Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are " more numerous " than the natural numbers.

To attain the latter rank at the age of 34 was a notable accomplishment, but Cantor desired a chair at a more prestigious university, in particular at Berlin, at that time the leading German university.

In one of his earliest papers, Cantor proved that the set of real numbers is " more numerous " than the set of natural numbers ; this showed, for the first time, that there exist infinite sets of different sizes.

Between 1870 and 1872, Cantor published more papers on trigonometric series, and also a paper defining irrational numbers as convergent sequences of rational numbers.

He withdrew from public life in 747 to take up the monastic habit, " the first of a new type of saintly king ," according to Norman Cantor, " more interested in religious devotion than royal power, who frequently appeared in the following three centuries and who was an indication of the growing impact of Christian piety on Germanic society ".

In this case they often use the style The Reverend ; more usually, however, a cantor is called Cantor or Cantor Surname.

As Cantor and Dedekind were developing more abstract versions of Stevin's continuum, Paul du Bois-Reymond wrote a series of papers on infinitesimal-enriched continua based on growth rates of functions.

At the same time, more popular " big name " artists were hired to record for the label including Wilbur Sweatman, Eddie Cantor, the Six Brown Brothers, and the Louisiana Five.

In this way, results apply not only to the set of real numbers or set of integers but to more general time scales such as a Cantor set.

Note that, commonly, 2 < sup > ω </ sup > is referred to simply as the Cantor set, while the term Cantor space is reserved for the more general construction of D < sup > S </ sup > for a finite set D and a set S which might be finite, countable or possibly uncountable.

Mistakes and philosophical weaknesses in reasoning about infinitesimal numbers in the work of Gottfried Leibniz, Johann Bernoulli, Leonhard Euler, Augustin-Louis Cauchy, and others were the reason that they were originally abandoned for the more cumbersome real number-based arguments developed by Georg Cantor, Richard Dedekind, and Karl Weierstrass, which were perceived as being more rigorous by Weierstrass's followers.

A similar relationship between the projective hierarchy and the relativized analytical hierarchy holds for subsets of Cantor space and, more generally, subsets of any effective Polish space.

This was proven by Georg Cantor in his 1874 uncountability proof, part of his groundbreaking study of different infinities, and later more simply in his diagonal argument.

As with many other episodes in the series, " Thirty Minutes Over Tokyo " suggests that, in the end, the Simpsons are more attached to the local than to the global, and, as Cantor writes: " indeed the global is ultimately important in the series only insofar as it can be made local, that is, part of Springfield.

Some Christian theologians ( particularly neo-Scholastics ) saw Cantor's work as a challenge to the uniqueness of the absolute infinity in the nature of God — on one occasion equating the theory of transfinite numbers with pantheism — a proposition which Cantor vigorously rejected.

They both postulated that if the stars in the universe were distributed in a hierarchical fractal cosmology ( e. g., similar to Cantor dust )— the average density of any region diminishes as the region considered increases — it would not be necessary to rely on the Big Bang theory to explain Olbers ' paradox.

— The paradox told as a humorous narrative, featuring a hotel owner and a building contractor based on the feuding 19th-century mathematicians Georg Cantor and Leopold Kronecker

* Cantor, oral address Cantor ( some cantors use The Reverend as style, as above ) — Jewish cantors

" Shakespeare scholar Paul A. Cantor argues that this association is appropriate — the warlike Klingons find their literary matches in the characters Othello, Mark Antony, and Macbeth — but that it also reinforces a claim that the end of the Cold War means the end of heroic literature such as Shakespeare's.

Based on Merovingian ad hoc arrangements, using the form missus regis ( the " king's envoy ") and sending a layman and an ecclesiastic in pairs, the use of missi dominici was fully exploited by Charlemagne ( ruling 768 — 814 ), who made them a regular part of his administration, " a highly intelligent and plausible innovation in Carolingian government ", Norman F. Cantor observes, " and a tribute to the administrative skill of the ecclesiastics, such as Alcuin and Einhard ".

After marrying long-time girlfriend — law student Rianna Jennifer Cantor — in June 2002, Ponting credited her as the reason for his increased maturity.

Ethel Shutta ( pronounced " shoo-tay ") ( December 1, 1896 — February 5, 1976 ) was an American actress and singer, who came to prominence through her performances on Jack Benny's radio show, her role in the early Eddie Cantor musical Whoopee !, and her Broadway comeback in Follies at the age of 74.

Born and raised in Buffalo, NY, Nile came from a musical family — his grandfather was a vaudeville pianist who played with Bill " Bojangles " Robinson and Eddie Cantor ; his uncles played boogie-woogie.

Presently, seven of the nine top Republican leaders — Majority Leader Eric Cantor, Chief Deputy Whip Peter Roskam, Conference Chairman Jeb Hensarling, Conference Vice-Chairwoman Cathy McMorris Rodgers, Conference Secretary John Carter, Policy Committee chairman Tom Price, and National Republican Congressional Committee chairman Pete Sessions -- are members of the RSC.
