Let G be a locally compact unimodular group, and let {Ug} be a projective representation of G in the Hilbert space ℋ. Let ℋ0 ⊆ G be a compact subgroup. Then, a POVM P(dω) with outcome space Ω = G/H0 is covariant if and only if it has the form (13.26)P(dω)=Ug(...
Known as "Point Nemo", Latin for "no one" and also a reference to Jules Verne's Captain Nemo, it lies more than 1,400 nautical miles from the nearest land. This point was featured in the short story, The Call of Cthulhu, by H. P. Lovecraft as the location of the fictional city ...
