Projective unitary group
In mathematics, the projective unitary group PU(n) is the quotient of the unitary group U(n) by the right multiplication of its center, U(1), embedded as scalars.
Abstractly, it is the holomorphic isometry group of complex projective space, just as the projective orthogonal group is the isometry group of real projective space.

In terms of matrices, elements of U(n) are complex n×n unitary matrices, and elements of the center are diagonal matrices equal to eiθI, where I is the identity matrix. Thus, elements of PU(n) correspond to equivalence classes of unitary matrices under multiplication by a constant phase θ.
This space is not SU(n) (which only requires the determinant to be one), because SU(n) still contains elements eiθI where eiθ is an n-th root of unity (since then det(eiθI) = eiθn = 1).

Abstractly, given a Hermitian space V, the group PU(V) is the image of the unitary group U(V) in the automorphism group of the projective space P(V).

Isometry group
In mathematics, the isometry group of a metric space is the set of all bijective isometries (that is, bijective, distance-preserving maps) from the metric space onto itself, with the function composition as group operation. Its identity element is the identity function. The elements of the isometry group are sometimes called motions of the space.

Every isometry group of a metric space is a subgroup of isometries. It represents in most cases a possible set of symmetries of objects/figures in the space, or functions defined on the space. See symmetry group.

A discrete isometry group is an isometry group such that for every point of the space the set of images of the point under the isometries is a discrete set.

In pseudo-Euclidean space the metric is replaced with an isotropic quadratic form; transformations preserving this form are sometimes called "isometries", and the collection of them is then said to form an isometry group of the pseudo-Euclidean space.

From the 9000 m² large area, Mierendorffstraße runs in the direction of Charlottenburg Castle and Kaiserin-Augusta-Allee in the direction of Moabit. It was named in 1950 after the social democratic politician, social scientist and writer Carlo Mierendorff.

The bourgeois residential area around the square is also popularly known as the Mierendorff-Kiez. The historical name of the place, Kalowswerder, however, is hardly still common.

Carlo Mierendorff
Carlo Mierendorff (24 March 1897 – 4 December 1943) was a German politician of the Social Democratic Party (SPD) during the Weimar Republic. An intellectual activist and regional politician in the People's State of Hesse, he played a major role in the propaganda of the SPD and the anti-fascist Iron Front during the last years of the republic. He was elected to the Reichstag in 1930. After the Nazi rise to power, he was arrested and spent several years in concentration camps before being released in 1938. He then helped organise the underground resistance to the Nazi regime until his death in December 1943 in an Allied air raid on Leipzig.

Apple A8X
The Apple A8X is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, and manufactured by TSMC.

Club Fantastic Megamix
"Club Fantastic Megamix" is a medley single released by Wham! on 25 November 1983, and was the last single release for the duo on Innervision Records. It was mixed by DMC's Alan Couthard and approved by Mark Dean, the manager of Innervision Records. 
The single was released three months after Wham! had begun proceedings to leave the label, and was disapproved of by George Michael and Andrew Ridgeley. The single, which consisted of a mix of the tracks "A Ray of Sunshine", "Love Machine" and "Come On" from the album Fantastic, reached number 15 on the UK Singles Chart.

The only reason why the "Club Fantastic Megamix" was able to be issued was because the songs had already been released. Prior to a song being released, a publisher has the right to grant the first license of a tune of which he holds the copyright. Because those three songs had already been released to the public, the songwriter was unable to prevent the record company from creating this second release.

Innervision Records
Innervision Records was an independent record label distributed by CBS Records. The label was established around 1981 by Mark Dean and Shamsi Ahmed. Perhaps the most recognizable artist associated with Innervision was Wham!, who scored four top-ten hits while signed to the label.

Additional Innervision artists included Jimmy the Hoover, who had a top 20 hit with "Tantalise"; and the groups Animal Nightlife, the Promise, Girl Talk, and Space Monkey. Innervision released its last single in 1985, by that time the label's records were being distributed by EMI.
