If a 3-manifold has trivial fundamental group and the homology groups of the 3-sphere, is it necessarily homeomorphic to the 3-sphere? (680 hits)

"And if ever the suspicion of their manifold being dawns upon men of unusual powers and of unusually delicate perceptions, so that, as all genius must, they break through the illusion of the unity of the personality and perceive that the self is made up of a bundle of selves, they only have to say so and at once the majority puts them under lock and key, calls science to aid, establishes schizomania and protects humanity from the necessity of hearing the cry of truth from the lips of these unfortunate persons. Why then waste words, why utter a thing that every thinking man accepts as self-evident, when the mere utterance of it is a breach of taste? A man, therefore, who gets so far as making the supposed unity of the self two-fold is already almost a genius, in any case a most exceptional and interesting person. In reality, however, every ego, so far from being a unity is in the highest degree a manifold world, a constellated heaven, a chaos of forms, of states and stages, of inheritances and potentialities. It appears to be a necessity as imperative as eating and breathing for everyone to be forced to regard this chaos as a unity and to speak of his ego as though it were a one-fold and clearly detached and fixed phenomenon. Even the best of us shares this delusion."

Yeah. Perelman's the man.

What about 8-spheres and gate jumps?

Did you mean "homomorphic" or "homoerotic"?
_____________________________________________
Homeomorphic is similar to "equivalent" in a topological sense... but why say "equivalent" when you can say "homeomorphic"?
----------------------------------------------
Yea, but "homeoerotic" wouldn't be very funny would it?

Yes. Yes it is. Though I think the driveshaft is stuck. I'm not sure.

On a related note, this guy told me his meat-manifold was homeomorphic to your mother's ass.
