*18.02 Multivariable Calculus* and *18.03 Differential Equations* or *18.032 Differential Equations*

### Description

Complex analysis is a beautiful, tightly integrated subject. It revolves around complex analytic functions. These are functions that have a complex derivative. Unlike calculus using real variables, the mere existence of a complex derivative has strong implications for the properties of the function.

Complex analysis is a basic tool in many mathematical theories. By itself and through some of these theories it also has a great many practical applications.

There are a small number of far-reaching theorems that we’ll explore in the first part of the class. Along the way, we’ll touch on some mathematical and engineering applications of these theorems. The last third of the class will be devoted to a deeper look at applications.

The main theorems are Cauchy’s Theorem, Cauchy’s integral formula, and the existence of Taylor and Laurent series. Among the applications will be harmonic functions, two-dimensional fluid flow, easy methods for computing (seemingly) hard integrals, Laplace transforms, and Fourier transforms with applications to engineering and physics.

### Textbook

There is no required textbook. We will use the following written resources:

- Lecture Notes
- We will occasionally use readings from the following online textbooks. You can also use them as supplemental reading.
- Taylor, Michael.
*Introduction to Complex Analysis*(PDF - 1.3MB) - Beck, Matthias, Gerald Marchesi, Dennis Pixton, and Lucas Sabalka.
*A First Course in Complex Analysis*(PDF - 1.5MB)

- Taylor, Michael.
- Brown, James Ward and Ruel V. Churchill.
*Complex Variables and Applications.*9th ed. McGraw-Hill Education, 2013. ISBN: 9780073383170.

### Homework and Exams

There are nine problem sets, two one-hour in-class exams, and a three-hour final exam.

### Collaboration

MIT has a culture of teamwork. We encourage you to work with study partners.

- Collaboration on homework is encouraged.
- You must write your solutions yourself, in your own words.
- You must list all collaborators and outside sources of information.

Remember it it is a serious violation of academic integrity to copy an answer without attribution.
