Office Hours

All office hours are in my office (Albee 315).

Textbook Information

The textbook is Complex Variables and Applications by James Brown and Ruel Churchill. You will need a copy of the textbook for reading and homework problems, but you do not need to bring it to class. Any edition of the textbook will suffice for reading (it is currently in its 9th edition), but I will be using the 8th edition for assigning homework problems. You can buy a paperback copy book from Amazon.com for around $30, or a hardcover copy for about $105.

Course Policies

Introduction

This course will cover the basic theory of functions of one complex variable. Topics will include the geometry of complex numbers, holomorphic and harmonic functions, Cauchy’s theorem and its consequences, Taylor and Laurent series, singularities, residues, elliptic functions and/or other topics as time permits.

Prerequisites

The prerequisites are a familiarity with partial derivatives and with Taylor series. Any one of Math 241, Math 245, or Physics 221 should be sufficient.

Homework

There will be a written homework assignment due each Friday. You are encouraged to work with other students in solving the homework problems, but you should write your own solutions, and you must acknowledge anyone that you work with. Your solutions should be written clearly and in complete sentences, with enough detail that another student in the class would be able to follow your reasoning. You are encouraged to write your homework solutions in LaTeX, but this is not required.

Exams and Grading

The grade will be based on the weekly homework and two exams:

Homework 50%
Midterm Exam 25%
Final Exam 25%

The exams will most likely have both a takehome component and an in-class component.
