Textbook

Complex Analysis by E. Stein and R. Shakarchi Other good books are: Ahlfors's Complex Analysis, and Conway's Functions of one complex variable.


Grading

Your grade will be based on several homework assignments (30%), one Midterm (30%) and a Final exam (40%). The exams will most likely be in class.


Office Hours

I'll be available from 2-4:00 on Monday afternoons. You can also email me and schedule an appointment. The CA for our course is Ian Petrow. His office is in 381-B, and he will hold office hours on Wednesdays 1-3.

Midterm

The midterm will be on Tuesday November 1. It'll be inclass, and closed book/notes. It will cover Chapters 1-3, 5, and Appendix B of the book plus other material discussed in class (e.g. the homology form of Cauchy's theorem, and the general discussion of holomorphic functions with prescribed zeros etc). Midterm and Solutions.

Final

The final exam will be on Wednesday, December 14 from 7 to 10 PM.

Homework Assignments

Homework will be assigned every Tuesday, and due the following Tuesday. I will not accept late assignments. I know everyone is likely to have an off-week, and I will drop your lowest score.
  • Homework 1: Due Tuesday October 11. Do ten from the following problems. Chapter 1: Exercises 6, 7, 9, 10, 11, 16(d,e,f). Chapter 2: Read Section 2.3. Exercises 2, 5, 7, 8, 13. Chapter 2. Problems 1(a), 2. (These two problems are required for Math grad students). Solutions due to Emil Baronov.
  • Homework 2: Due Tuesday October 18. Chapter 3: Exercises 1, 14, 15, 16, 17. Also read Section 3.2.1, and do either (a) five of exercises 2-12 from Chapter 3, or (b) three of exercises 2-12 from Chapter 3 and Problem 3 from Chapter 3. Math grad students must do option (b). Solutions due to Emil Baronov.
  • Homework 3: Due Tuesday, October 25. Chapter 2: Exercise 10, Problem 4. Chapter 3: Exercises 18, 21, 22. Chapter 5: Exercises 3,5, and Problem 1.

    Additional Problem: Consider the region R obtained by removing the interval [-1,1] from the complex plane. Prove that on R one can define a holomorphic function log ((z+1)/(z-1)). Prove that one can define a holomorphic function \sqrt(1-z^2) on this region. Let gamma denote a cycle in R. What are the possible values of the integral around gamma of 1/\sqrt{1-z^2}?

    Solutions due to Emil Baronov.

  • Homework 4: Due Tuesday November 1. Chapter 5: Exercises 1, 6, 7, 10, 11, 13, 17 (In part b, there is a typo and the first term in the definition of F should have E'(0) in the denominator.) Chapter 5: Problems 3 and 4. For Problem 3 you may find Stirling's formula helpful, and may assume any useful version of it.

    Solutions due to Emil Baronov.

  • Homework 5: Due Tuesday, November 8. Chapter 6: Exercises 1, 3, 5, 7, 10, 12, 15, 17. Chapter 6: Problems 2 and 3.

    Solutions due to Emil Baronov.

  • Homework 6: Due Tuesday, November 15. Chapter 6: Exercise 16. Problem 1 (there's a typo in part a, and it should be N^{1-s} instead of N^{s-1}). Chapter 7: Exercises 1, 2, 3, 5, 6, 7 (read Schwarz's reflection principle Chapter 2, section 5.6), 8.
  • Homework 7: Due Tuesday, November 29. Chapter 8: Exercises 3, 4, 10, 11, 12, 13, 15. Problems 2 and 5.
  • Homework 8: Due Tuesday, December 6. Chapter 8: Exercises, 20, 24 a,b. Problem 9. Chapter 9. Exercises 1, 2, 4, 5. Problem 4.
