These complex structures have embedded elliptic curves, so they won't be isomorphic to $\Bbb C^2 \setminus 0$ after removing a point. However, I doubt that they have compact quotients. | |

| May 12, 2020 at 1:27 | comment | added | Danny Ruberman | Only marginally less silly: take a cyclic group acting linearly and freely on $C^2 \setminus \{0\}$. | |

Isn't $\mathbb C^2 \setminus \{0\}$ a silly example of (i)? (Also, \backslash doesn't space well: $\mathbb C^2 \backslash \{0\}$. Prefer \setminus: $\mathbb C^2 \setminus \{0\}$. I have edited accordingly.)

\backslash -> \setminus
