## Any two curves over k homeomorphic [closed]

Why are two curves over a field k homeomorphic?

I have been able to prove that any variety of positive dimension over a field k has the same cardinality as k.

Can you give a simple description of the Zariski topology of a curve? – Hurkyl Sep 23 2011 at 1:40
Rather than create new tags "algebraic" and "geometry" I fixed the tagging – David White Sep 23 2011 at 2:51

A bijection between two topological spaces $f:X \rightarrow Y$ where open sets are complements of finite sets is a homeomorphism.
