| Aims |
The introduction by Riemann of a surface covering the complex plane on which an algebraic function w(z) solution of an irreducible polynomial equation P(z,w)=0 becomes single-valued and analytic, is at the basis of the modern concept of a variety. An abstract Riemann surface is defined as a complex connected one-dimensional variety. The aim of the course will be to establish that abstract compact Riemann surfaces are precisely the Riemann surfaces of algebraic functions. The proof will be done by using the tools of modern topology (covering spaces) and algebraic geometry (sheaf cohomology). We will also discuss the relation between compact Riemann surfaces and soliton theory.
