| Mar 27, 2011 at 13:29 | comment | added | Jino | sorry. I's an error. The fibration is $X \rightarrow E \rightarrow S^n$ | |
| Mar 27, 2011 at 11:33 | comment | added | José Figueroa-O'Farrill | The sequence you have written is not, however, one with fibre $S^n$, but rather one with fibre $X$ and base $S^n$. If you really mean $S^n \to X \to B$, then the sequence is $$ \cdots \to \pi_{n+1}B \to \pi_n S^n \to \pi_n X \to \pi_n B \cdots$$. | |
| Mar 27, 2011 at 11:18 | comment | added | Jino | Sean : any fibration $X \rightarrow B$ with fibre $S^n$ | |
