| Jul 9, 2010 at 11:44 | comment | added | Anweshi | I didn't mean to imply that there is a Poincare duality for fractals. In fact I know almost nothing about fractals. All I wanted to say was that there is an interesting proof of Poincare duality in terms of dual cells, and that it might interest you. | |
| Jul 9, 2010 at 7:10 | comment | added | Kerry | Hi. I know Poincare duality. But I don't believe one can define singular homology successfully for fractals for the simple reason they they are not continuous objects. So maybe I should search on this before raising the question. The second part got deleted by Daniel's request. I don't enough on this to "edit", so I delete it. | |

Being urged by one of the commenters, the second paragraph was deleted

| Jul 8, 2010 at 14:53 | comment | added | Anweshi | While we are at it, the cubical definition and subdivision in Massey's "Singular homology theory" might be of interest, just to see that you don't need to use simplexes. | |

| Jul 8, 2010 at 13:53 | comment | added | Tom Goodwillie | I think the OP has seen singular homology, and has seen the proof of the excision property in Hatcher's book. | |

| Jul 8, 2010 at 13:12 | comment | added | Johannes Hahn | There is more to life (as an algebraic topologist) than simplicial homology. In particular fractals probably (depending on your understanding of this word) have homology groups. The keyword is singular homology which generalises simplicial homology (and other types of homology) to arbitrary topological spaces. | |
