Center (group theory)

In abstract algebra, the center of a group, is the set of elements that commute with every element of . It is denoted , from German Zentrum, meaning center. In set-builder notation,


The center is a normal subgroup, . As a subgroup, it is always characteristic, but is not necessarily fully characteristic. The quotient group, , is isomorphic to the inner automorphism group, .

A group, is abelian if and only if . At the other extreme, a group is said to be centerless if is trivial; i.e., consists only of the identity element.

The elements of the center are sometimes called central.

Center (disambiguation)
Center (PAT station)

Center was a station on the Port Authority of Allegheny County's light rail network, located in Bethel Park, Pennsylvania. The street level stop was designed as a small commuter stop, serving area residents who walked to the train so they could be taken toward Downtown Pittsburgh.

Center was one of eleven stops closed on June 25, 2012 as part of a system-wide consolidation effort.

Center (algebra)

The term center or centre is used in various contexts in abstract algebra to denote the set of all those elements that commute with all other elements. It is often denoted Z, from German Zentrum, meaning "center". More specifically:

  • The center of a group G consists of all those elements x in G such that xg = gx for all g in G. This is a normal subgroup of G.
  • The similarly named notion for a semigroup is defined likewise and it is a subsemigroup.
  • The center of a ring R is the subset of R consisting of all those elements x of R such that xr = rx for all r in R. The center is a commutative subring of R, and R is an algebra over its center.
  • The center of an algebra A consists of all those elements x of A such that xa = ax for all a in A. See also: central simple algebra.
  • The center of a Lie algebra L consists of all those elements x in L such that [x,a] = 0 for all a in L. This is an ideal of the Lie algebra L.
  • The center of a monoidal category C consists of pairs (A,u) where A is an object of C, and u : A ⊗  −  →  −  ⊗ A a natural isomorphism satisfying certain axioms.
Center (basketball)

The center (C), also known as the five or the big man, is one of the five positions in a regulation basketball game. The center is normally the tallest player on the team, and often has a great deal of strength and body mass as well.

The tallest player to ever be drafted in the NBA or the WNBA was the 7'8" (2.33 m) Yasutaka Okayama from Japan, though he never played in the NBA. The tallest players to ever play in the NBA, at 7'7" (2.31 m), are centers Gheorghe Mureșan, and Manute Bol. Standing at 7'2" (2.18 m), Margo Dydek is the tallest player to have ever played in the WNBA.

Center (gridiron football)

Center (C) is a position in American football and Canadian football (in the latter the position is spelled centre, following Commonwealth spelling conventions). The center is the innermost lineman of the offensive line on a football team's offense. The center is also the player who passes (or " snaps") the ball between his legs to the quarterback at the start of each play.

In recent years, the importance of centers for a football team has increased, due to the re-emergence of 3-4 defenses. According to Baltimore Ravens general manager Ozzie Newsome, "you need to have somebody who can neutralize that nose tackle. If you don't, everything can get screwed up. Your running game won't be effective and you'll also have somebody in your quarterback's face on every play."

Center (band)

Center (or Tsentr, Russian: Центр) is a Russian-speaking band, which can be described as eclectic and experimental. The styles of their music are very different, starting with new wave and Russian rock in the early years, crossing over to electronica.

Center was founded by Vasily Shumov in Moscow, Russia in the late 1970s. The first band name was "777". In the early 1980s Center became popular in the Soviet music underground. The band released over 25 albums, created music for films and TV, appeared on TV shows, and performed in Europe and America. Center is documented in numerous publications and books.

In the 1990s, the band leader Shumov moved from Moscow, Russia to Los Angeles, United States where he continued his music and art work.

An album "Plastikozamenitel'" ("Plastic substitute") from 2000 is the first release of Center that features the new concept of so-called Centroborators. Centroborators are the artists from various locations, who contribute to the albums of Center, transferring their digital recordings to Vasily Shumov's studio using internet. Several albums after "Plastikozamenitel" were created using the Centroborators concept.

Numerous albums by Center and Shumov are available on CDs and as MP3 files for free download from the band's official web site.

Since the mid-2000s, the band recommenced activities in Russia.

Center (category theory)

Let C = (C,  ⊗ , I) be a (strict) monoidal category. The center of C, also called the Drinfeld center of C and denoted Z(C), is the category whose objects are pairs (A,u) consisting of an object A of C and a natural isomorphism u : A ⊗ X → X ⊗ A satisfying

u = (1 ⊗ u)(u ⊗ 1)


u = 1 (this is actually a consequence of the first axiom).

An arrow from (A,u) to (B,v) in Z(C) consists of an arrow f : A → B in C such that

v(f ⊗ 1) = (1 ⊗ f)u

The category Z(C) becomes a braided monoidal category with the tensor product on objects defined as
