Domain wall

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 (band)

Domain is a German power metal band.

History

1986–1992

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".

2000–2006

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…

Domain of a function

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.

Formal definition

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.

Natural (Peter Andre album)

Natural is the second studio album released by the Australian singer-songwriter Peter Andre.

Background

Following the success of his first album in Australia, Andre was commissioned to record a second album with Melodian. However, Melodian believed that it would be wise to see if he could break the British market as well. Andre signed a joint deal with Melodian and the British record label, Mushroom UK, for his second studio album to be released in both markets. On 1 May 1995, a single, entitled "Turn It Up" was released to both markets, achieving Top 10 success on both countries' singles charts. However, the deal with Mushroom soon came under jeopardy when the label went into administration. Melodian pressed ahead with releases in Australia, releasing "Mysterious Girl" on 1 September 1995.

Natural (T-Square album)

Natural is the fifteenth studio album by Japanese Jazz fusion band T-Square. It was released on May 1, 1990. It was the last to feature Takeshi Itoh on Saxophone, during his initial run with the band (from 1977 to 1990). He returned to T-Square in mid-2000 and has been performing with the group ever since.

Natural (The Special Goodness album)

Natural is the fourth studio album by American alternative rock band The Special Goodness, released on May 22, 2012 on Surf Green Records. Upon the album's release, Patrick Wilson noted, "You can get a six-inch turkey from Subway and be happy for thirty minutes, or get the new The Special Goodness and be happy forever."

Background and recording

The album was recorded solely by founding member Patrick Wilson, with Wilson noting, "At some point, I just sort of stopped trying to make [the Special Goodness] a band and just said, 'I'm not going to be happy unless I do everything myself,' which is totally ironic because that's not really my personality."

Release

Prior to its release, the album was available to stream on Spotify. There are currently no physical copies of the album available.
