To do: add section on Lie algebra, and one on representations of the Lorentz group. Discuss relationship of the Lorentz group to special and general relativity. -- Fropuff 16:45, 11 Feb 2004 (UTC)
Connectedness
It is a 6-dimensional noncompact Lie group which is neither connected, nor simply connected.
Can something be simply connected without being connected? Josh Cherry 04:44, 18 Nov 2004 (UTC)
Technically speaking, no. What is meant is that the connected components of the Lorentz group are themselves not simply connected. We could say this instead but it's a little more wordy. -- Fropuff 06:21, 2004 Nov 18 (UTC)
- I've changed this. Maybe it's just me, but what was there left me scratching my head, much as though someone had said this number is neither an integer, nor an even integer. Josh Cherry 23:54, 18 Nov 2004 (UTC)
