Homework assignments should be submitted to the mailbox of the grader, John Kopper, by 4:00pm on the due date. The mailroom is located on the 3rd floor of SEO. Late homework is not accepted.

Unless otherwise noted, all problems refer to the main textbook, Complex Analysis, 3rd Edition, by Lars Ahlfors. Problems are listed using notation like

Sec 1.2.4(p20): 3, 5
which means
In Chapter 1, section 2.4, the list of exercises begins on page 20.
Complete problems 3 and 5 on this list.

Please make sure to write clearly and that the assignment number and your name appear at the top of the first page. Staple your homework if it spans several sheets of paper. Typeset solutions are welcome, but not required.

By the end of the first week, read chapter 1 and the first two sections from chapter 2.

After that, we will for the most part proceed linearly through the textbook at a steady rate. The sections under discussion will be announced in each lecture, and it is up to you to keep up with the corresponding reading.

Any sections to be skipped or material to be covered out of order will be announced in advance. The following announcements of this type have been made:

• No lectures about section 3.1.
