A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model. Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is the metastable vacuum.
A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.
Important examples are:
Besides these important cases similar solitons appear in wide spectrum of the models. Here are other examples:
Domain is a German power metal band.
Domain first impressed fans of melodic metal back in the 1980s with their first works, "Lost In The City" (still under the old band name Kingdom), "Before The Storm" and "Crack in The Wall", as well as with their hit songs such as 'Lost In The City' and ‚ 'I Don’t Wanna Die'. Single "Heart Of Stone was a title song of german mini-serial "Bastard".
But it was their next albums, "One Million Lightyears From Home" (2001), "The Artefact" (2002) and "The Sixth Dimension" (2003) as well as a successful tour with the rock legends, Glenn Hughes and Joe Lynn Turner (HTP) that secured the quintet a place in the European Melodic Metal scene. With a harder edged sound, Domain still had a good following. And that was when the career of the guitarist Axel "Ironfinger" Ritt (Grave Digger), ex-vocalist Carsten Lizard Schulz (Evidence One et al.), and the long-term band mates keyboarder Erdmann Lange, ex-bass player Jochen Mayer (Boysvoice, Demon Drive, Casanova) and the ex-drummer Stefan Köllner really began…
In mathematics, and more specifically in naive set theory, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined. That is, the function provides an "output" or value for each member of the domain. Conversely, the set of values the function takes on as output is termed the image of the function, which is sometimes also referred to as the range of the function.
For instance, the domain of cosine is the set of all real numbers, while the domain of the square root consists only of numbers greater than or equal to 0 (ignoring complex numbers in both cases). When the domain of a function is a subset of the real numbers, and the function is represented in an xy Cartesian coordinate system, the domain is represented on the x-axis.
Given a function f:X→Y, the set X is the domain of f; the set Y is the codomain of f. In the expression f(x), x is the argument and f(x) is the value. One can think of an argument as an input to the function, and the value as the output.
Summit is a historic home located at Catonsville, Baltimore County, Maryland. It a large brick house, once part of a country estate owned by James Albert Gary. It features a three-story Italianate tower and large wing extending to the rear. The main façade is three stories and five bays wide, with the tower located on the east side. A one-story porch with square columns and railings runs across the full façade. The mansion was built originally as a summer home and later converted to apartments after its sale to the Summit Park Company in 1919.
It was listed on the National Register of Historic Places in 1979.
The Lakewood Church Central Campus (originally The Summit and formerly Compaq Center) is a house of worship in Houston, Texas. It is located about five miles southwest of Downtown Houston, next to the Greenway Plaza.
From 1975 to 2003 the building served as a multi-purpose sports arena, for various professional teams in Houston.
From its opening until 1998, the building was known as The Summit. Computer technology firm Compaq bought naming rights to the building after that and it was known as Compaq Center until 2003. At that point the name was dropped, coinciding with opening of the Toyota Center as a new professional sports venue in Houston. Shortly after, the building was leased out to Lakewood Church for use as its main facility. Lakewood Church purchased the building outright in 2010.
In 1971, the National Basketball Association's San Diego Rockets were purchased by new ownership group Texas Sports Investments, who moved the franchise to Houston. The city, however, lacked an indoor arena suitable to host a major sports franchise. The largest arena in the city at the time was 34-year-old Sam Houston Coliseum, but the Rockets would not even consider using it as a temporary facility. Plans were immediately undertaken to construct the new venue that would become The Summit. The Rockets played their home games in various local facilities such as Hofheinz Pavilion and the Astrodome during the interim.
Summit is an album by Argentinean bandoneonist Astor Piazzolla and jazz saxophonist Gerry Mulligan. The original LP was recorded and released in Italy in 1974.
The album was born from the meeting, which took place in Italy in 1974, between the Argentinean bandoneon player Astor Piazzolla and the North American saxophonist Gerry Mulligan, considered among the most prominent members of the world music scene.
The album was recorded in Milan and includes eight compositions, seven written by Piazzolla and one by Mulligan. The fusion of the nuevo tango of Astor Piazzolla with the jazz influences of Gerry Mulligan, backed by an orchestra of Italian and Argentinian musicians, has been described as "a memorable disc of rare beauty" and "a one-off event, wholly successful".
The album was recorded on 24–26 September and 1–4 October 1974 at Mondial Sound Studio in Milan, Italy, by sound engineer Tonino Paolillo.
The release history of Summit appears somewhat loose. The LP was originally released in 1974 on the Italian label Erre T.V. Besides a release on the short-lived label of the German chemical company BASF the album was re-released the following year by the German WEA on the Atlantic Records label as Tango Nuevo. In Latin America the album was released as Reunión cumbre on the Venezuelan label Trova and (without further title) in Brazil on Pick Jazz. Although several times reissued on CD since the late 1980s the album was not digitally remastered yet.
