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.
The Room mansion (房宿, pinyin: Fáng Xiù) is one of the Twenty-eight mansions of the Chinese constellations. It is one of the eastern mansions of the Azure Dragon.
Room is a 2005 independent drama film written and directed by Kyle Henry and starring Cyndi Williams. An overworked, middle-aged Texas woman embezzles from her employer and abandons her family to seek out a mysterious room that has been appearing to her in visions during seizure-like attacks.

Room (formerly Room of One's Own) is a Canadian quarterly literary journal that features the work of emerging and established women and genderqueer writers and artists. Launched in Vancouver in 1975 by the West Coast Feminist Literary Magazine Society, or the Growing Room Collective, the journal has published an estimated 3,000 women, serving as an important launching pad for emerging writers. Currently, Room publishes short fiction, creative non-fiction, poetry, art, feature interviews, and features that promote dialogue between readers, writers and the collective, including "Roommate" (a profile of a Room reader or collective member) and "The Back Room" (back page interviews on feminist topics of interest). Collective members are regular participants in literary and arts festivals in Greater Vancouver and Toronto.
The journal's original title (1975-2006) Room of One's Own came from Virginia Woolf's essay A Room of One's Own. In 2007, the collective relaunched the magazine as Room, reflecting a more outward-facing, conversational editorial mandate; however, the original name and its inspiration is reflected in a quote from the Woolf essay that always appears on the back cover of the magazine.
