• curprev 03:2603:26, 3 May 2024 Aavoronov talk contribs 12,599 bytes −7 →Split orthogonal group: Changed the vague and somewhat misleading statement "The case (1, 1) corresponds to the multiplicative group of the split-complex numbers" with "The group SO(1, 1) may be identified with the group of unit split-complex numbers." The original phrase was misleading, because it could be interpreted as to suggest that the group O(1,1) is identified with the multiplicative group D* of split-complex numbers, which is not correct: dim O(1,1) = dim SO(1,1) =1 and dim D^*=2. undo
