Here's more cowbell.
I have highlighted a few words. All other emphasis is as in the originals.
As can be seen from the examples above, different authors use slightly different definitions. By Warner's definition, all locally Euclidean spaces are Hausdorff, but Lee notes that locally Euclidean
spaces need not be Hausdorff.
All three authors agree, however, that locally Euclidean
manifolds are Hausdorff. It's part of their definition.
Mathematicians are fond of generalization, so they sometimes consider what would happen if the definition of a manifold were relaxed to allow non-Hausdorff spaces. There is a
Wikipedia article on non-Hausdorff manifolds, which starts out by acknowledging this fact:
ProgrammingGodJordan is having trouble not only with mathematics, but also with the challenge of quoting other participants in this thread accurately. For example:
Actually, I said the particular supermanifold you appeared to be citing (via Wikipedia) isn't Euclidean, because it isn't even Hausdorff.
That's true.
Euclidean spaces are Hausdorff. Spaces that are not Hausdorff are therefore not Euclidean.
It's called logic. Try it sometime.
I have not used the word "fabric" in this discussion. I have never before heard someone use the phrase "Riemannian fabric".
A Google search on that two-word phrase turns up 5 results, with this thread as top hit. The other four hits include a site of which Google warns "This site may harm your computer", plus a "deconstructing God" blog whose most recent entry, dated Jury 6th, 2009, consists of gibberish under the title "Appreciating Michael Jackson".
No. You are quite confused. As I said to
RealityCheck, all Riemannian manifolds are locally Euclidean.
The fibers can be Euclidean even if the manifold is not.
It is trivially observable that none of my previous posts within this thread have used the word "fabric".
It is trivially observable that I have never written the sequence of words within your quotes, in this thread or in any other.
Crackpots often invent quotations because it's easier to attack stupid stuff they've invented out of thin air than what others have actually written or said.
