MWF, 1:10-2:00 PM. MSB, 2112. First lecture: April 2.
Instructor: M. Kapovich
Special TA: Y. Lai
Well, a Riemann surface is a
certain kind of Hausdorff space. You know what a
Hausdorff space is, don’t you?
Its also compact, ok. I guess it is also a manifold.
Surely you know what a manifold
is. Now let me tell you one non-trivial theorem,
the Riemann–Roch Theorem.
— Gian-Carlo Rota’s recollection of Lefschetz lecturing in the
1940’s, quoted in
Beautiful Mind by Sylvia Nasar.
The main objectives of the course are:
1. Uniformization theorem for Riemann surfaces.
2. Riemann-Roch theorem for Riemann surfaces.
3. Ahlfors-Schwartz lemma: Curvature, distance and conformality.
4. Introduction to Teichmuller spaces and moduli of Riemann surfaces.
I will try to make the treatment of the Uniformization theorem and
Riemann-Roch as elementary as possible, avoiding harmonic analysis and
All the tools that we will need are: the Riemann mapping theorem,
reflection principle, convergence for normal families of holomorphic
maps, residues of meromorphic functions and intergation of differential
forms along curves.
