There was a previous post on the correspondence between Riemann surfaces and algebraic geometry. I want to ask a related but more detailed question. BACKGROUND: In the case of a genus 1 surface X there's a very explicit construction. Namely X can be realized as ℂ/L for a lattice L ≅ ℤxℤ. From here the Weierstrass p function and its derivative can be constructed http://en.wikipedia.org/wiki/Weierstrass%27s_elliptic_functions and these give you a map ℂ/L --> ℙ^2 via z |--> [p(z), p'(z), 1] which realizes X as a degree three curve in ℙ^2 QUESTION: Is there 1) a complex manifold Y that is a covering space of X such that X ≅ Y/G where G is the covering group of Y over X 2) holomorphic functions f₁, f₂, f₃ from Y/G to ℂ∪∞ such that z |--> [f₁,(z), f₂(z), f₃(z)] realizes X as a projective variety of dimension 1 in ℙ^2? I'm told a good choice for Y would be the hyperbolic plane because then the 4g-gon representation of a genus g surface tiles the plane. |

Analogues of the Weierstrass p function for higher genus compact Riemann surfacesThere was a previous post on the correspondence between Riemann surfaces and algebraic geometry.
