| Aug 4, 2015 at 14:03 | comment | added | arivero | @abx nice, so with $T^7 = T^4 \times T^3$ mi "motivation" has at least one answer if one can cover $S^3$; it seems I should look for generic families of actions. | |
| Aug 4, 2015 at 13:27 | comment | added | abx | $T^{2n}$ can be realized as a branched covering of $\mathbb{C}\mathbb{P}^n$ for all $n$: take a $n$-dimensional abelian variety embedded in some $\mathbb{C}\mathbb{P}^N$ and a generic projection to $\mathbb{C}\mathbb{P}^n$. | |
