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.

Žale

Žale Central Cemetery (Slovene: Centralno pokopališče Žale), often abbreviated to Žale, is the largest and the central cemetery in Ljubljana and Slovenia. It is located in the Bežigrad District and operated by the Žale Public Company.

History

The cemetery was built in 1906 behind Holy Cross Church. The first burial was performed in the same year on May 3, when the priest Martin Malenšek was transferred there from the old Navje cemetery.

During World War I, many of the fallen soldiers of all sides were buried in Žale. However, they were all Roman Catholics, while Protestants, Jews and Muslims were buried in Navje. In 1923 the authorities allowed Jews and Muslims to be buried in Žale too, but only on the exterior side of the cemetery wall.

In 1931 the new part of the cemetery (B part) opened. The Italian military cemetery was arranged there and many Italian soldiers were reburied from the A part. At the same year the Jewish part of the cemetery was arranged too, however it was separated from the main part by a fence. In 1939 the Ossuary of the victims of World War I was built by architect Edvard Ravnikar , where 5,258 of the victims of this war as well as of the associated conflicts were later buried.
