Math 6220: Complex Analysis


Instructor: Mladen Bestvina
Office: JWB 210
Office hours: By appointment. I'll also hang around after class for any brief questions.
Text: There are many complex analysis textbooks out there. They mostly cover the standard material (up to the Cauchy integral formula and consequences) in more or less the same way, and might differ in the additional material. I plan to cover hyperbolic geometry and use it to prove classical theorems such as Little and Great Picard theorems. I also plan to cover the Uniformization theorem. Here are some books that I'll be using:

I'll follow Stein-Shakarchi up to the Cauchy theorem, and then we'll see.
Meets
: MWF 2:00PM-2:50PM at CSC 25
Midterm
: Feb 28.

Final: Thursday, April 24, 2025, 1:00 – 3:00 pm
Grading: The final grade is based on homework (30%), problem session activity (10%), the midterm (20%) and the final (40%).

Homework: It will be assigned weekly. You are encouraged to work in groups, but what you write should be your own work and you should list the other people in your group. It will be due every week on Mondays at 9 am Tuesdays at 11:59pm and you should turn it in through canvas in latex. Late homework is not accepted but the lowest two scores are dropped from the count. You should read the assigned reading for the week before the corresponding lecture. I will also typically give out several problems each week that you are not required to turn in. We'll have a problem session every two weeks outside the class time where you are expected to present solutions to unassigned problems.

Problem sessions: Fridays 1-2 at CSC 25. There will be one approximately every two weeks.

Homework
