![Jese Leos](https://bookquester.com/author/greg-foster.jpg)
Complex analysis is an intriguing branch of mathematics that deals with complex numbers and their properties. If you've ever been curious about this captivating field, or if you are a beginner looking to enhance your understanding, then Twenty One Lectures On Complex Analysis is the perfect resource for you. In this article, we will explore the key concepts covered in these lectures and unravel the mysteries surrounding complex numbers.
Understanding Complex Numbers
Complex numbers are numbers that contain both a real part and an imaginary part. They are written in the form a + bi, where a represents the real part and b represents the imaginary part. The concept of complex numbers might seem daunting at first, but once you grasp the basics, you will unlock a whole new world of mathematical possibilities.
Exploring the Twenty One Lectures
The Twenty One Lectures On Complex Analysis cover a wide range of topics, carefully curated to provide a comprehensive understanding of the subject. Let's dive into some of the key lectures:

Lecture 1: to Complex Analysis
This lecture sets the foundation for the entire course. It introduces the complex plane, the algebraic properties of complex numbers, and the geometric interpretation of complex numbers. This is where you'll start building your knowledge from the ground up.
Lecture 5: Complex Functions
Complex functions are an essential part of complex analysis. In this lecture, you'll explore the concept of complex functions, including the definition, differentiability, and analyticity. You'll also delve into the Cauchy-Riemann equations and learn about the relationship between real and complex functions.
Lecture 10: Residue Theory
Residue theory is a powerful tool in complex analysis for evaluating complex integrals. This lecture introduces residue theory, explains residues and poles, and demonstrates how to apply residue theory in various scenarios. Understanding residue theory opens up a whole new range of applications in solving complex problems.
Lecture 15: Conformal Mappings
Conformal mappings are transformations that preserve angles between intersecting curves. In this lecture, you'll discover the fascinating world of conformal mappings and their applications. You'll learn about the mapping of circles, the Riemann mapping theorem, and explore different types of conformal mappings.
Lecture 20: Analytic Continuation
Analytic continuation is a technique used to extend the domain of a function to obtain new insights. This final lecture focuses on analytic continuation and explores its various applications. You'll learn about branch cuts, Riemann surfaces, and the concept of multivalued functions. Prepare to have your mind expanded as you dive into this exciting topic.

At its core, this concise textbook presents standard material for a first course in complex analysis at the advanced undergraduate level. This distinctive text will prove most rewarding for students who have a genuine passion for mathematics as well as certain mathematical maturity. Primarily aimed at undergraduates with working knowledge of real analysis and metric spaces, this book can also be used to instruct a graduate course. The text uses a conversational style with topics purposefully apportioned into 21 lectures, providing a suitable format for either independent study or lecture-based teaching. Instructors are invited to rearrange the order of topics according to their own vision. A clear and rigorous exposition is supported by engaging examples and exercises unique to each lecture; a large number of exercises contain useful calculation problems. Hints are given for a selection of the more difficult exercises. This text furnishes the reader with a means of learning complex analysis as well as a subtle to careful mathematical reasoning. To guarantee a student’s progression, more advanced topics are spread out over several lectures.
This text is based on a one-semester (12 week) undergraduate course in complex analysis that the author has taught at the Australian National University for over twenty years. Most of the principal facts are deduced from Cauchy’s Independence of Homotopy Theorem allowing us to obtain a clean derivation of Cauchy’s Integral Theorem and Cauchy’s Integral Formula. Setting the tone for the entire book, the material begins with a proof of the Fundamental Theorem of Algebra to demonstrate the power of complex numbers and concludes with a proof of another major milestone, the Riemann Mapping Theorem, which is rarely part of a one-semester undergraduate course.
