Dec 13	accepted	Real projection spaces
Dec 13	comment	Fundamental group of the connected sum of manifolds What happened when M, N are knot complements?
Dec 13	asked	Real projection spaces
Dec 13	comment	homotopy groups of mapping space Would do please be a little more specific? That will help a lot! Thanks!
Dec 12	comment	homotopy groups of mapping space Obviously I can't assume Y is an Eilenberg-Maclane space;and the result is to show the case when k$\le$n-m
Dec 12	comment	homotopy groups of mapping space I didn't see how that could help. I'm think of using $\sigma':(S^k\times X\to Y)$

Dec 5	comment	Fundamental group of the complement of Borromean rings I think I got it, using Wirtinger Presentation and get 6 relations, then reduce them to 3 as the form of commutators
Dec 5	comment	Fundamental group of the complement of Borromean rings it says that circle C links with circle A,B in a way as $aba^{-1}b^{-1}$, but I want to show that $[a,[b,c^{-1}]]=1$

Mar 17	comment	Infinite product formula for a complex function hmm, here I used En to the power n,to satisfies the multiplicity condition. it still converges right? Followed by the radius of convergence of $$\sum(a_n z^n)=\sum (na_n z^n)$$
