Non-commutativity of certain Hopf spaces Hey Justin!! ( So happy to find you here). This completes the proof. One remark though, One do not need to use Serre SS. I would say it follows by construction, James construction! |

Non-commutativity of certain Hopf spaces I do not know if I am hitting the right cord, but what I mean by commutative hopf algebra is that I have a homotopy between $H: \mu \simeq \mu \circ T$, where $T: \Omega(X) \times \Omega(X) \to \Omega(X) \times \Omega(X) $ is the switch map. |

Non-commutativity of certain Hopf spaces To start with I have to admit that the situation is very blurry to me at this moment. But I do mean multiplication by concatenation, the usual multiplication on a loop space, at least thats the multiplication I was thinking of. I do not understand what you mean when you say "exactly one point". |

Bar construction for spectra I did not know this, and certainly this is very interesting. It seems slightly out of context of what I am interested( which right now is hard to describe). But thanks for pointing this out. I will keep in mind. |

In the cohomology of Thom spectrum over LoopS^{2} and p-adic characteristic classes Sorry I should have mentioned this in the questioin, $G_{3}$ is the unit component of $ \Omega^{\infty}S_{3}$ where, $S^{3}$ is the $3$-adic sphere spectrum. |

Complementary Sets in $\mathbb{C}P^2$ I think, I was too fast to jump to conclusion, I am sorry about my previous comment. Though the statement is true if $M$ is simply connected. One thing which concludes that the above statement is true is $H_{2}(M) = 0$ with the required coefficient. Simply connected is one option. @Mathews: Can you elaborate on the kind of sets $U$ and $V$ are? Are they open? or a related problem that you are looking at if thats the case) |

Complementary Sets in $\mathbb{C}P^2$ If you mean '$ U \cup V = \mathbb{CP^{2}}$', then apply Mayer-Veitoris. Since $M$ is oriented $H_{2}(M)$ does not have any $2$ torsion. And the answer pops out. But I am sorry to say this not a mathoverflow problem. |

Complementary Sets in $\mathbb{C}P^2$ Why not, $U$ is just homotopic to the complement set. They may still interest. |
