https://doi.org/10.1007/978-3-531-91370-4 give here is due to Henrik Martens . There are more “geometric” proofs, some of which will be found in Griffiths-Harris or Arbarello-Cornalba-Griffiths-Harris . We begin with a general fact about complex tori.河潭 发表于 2025-3-28 22:34:28
The Sheaf of Germs of Holomorphic Functions,ch pairs (., .) and (., .) are said to be equivalent, and define the same germ of holomorphic function at a, if there exists an open neighbourhood . of ., . ⊂ . ∩ ., such that . = .. An equivalence class is called a germ of holomorphic function at .; the class of a pair (.) is called the germ of . acarbohydrate 发表于 2025-3-29 02:30:10
The Riemann Surface of an Algebraic Function,, then .is a finite covering (of .-sheets). In particular, π. (.. − .) has only finitely many connected components. Moreover, if . is a connected component of .’, then π’|. is again a covering, and so maps . onto P. − .. Hence .’ has only finitely many connected components.
