Double sections, dominating maps, and the Jacobian fibration. (English) Zbl 0967.32015
The authors give two parametrized versions of the uniformization theorem of a nonconstant, nonhyperbolic Riemann surface. The first constructs the uniformization map directly in terms of coordinates via classical complex analysis; the second one, which is coordinate independent, works over any complex curve and is obtained by extending Kodaira’s theory of the Jacobian fibration to a family of singular algebraic curves constructed via algebraic geometry.
