Applied and Computational Complex Analysis. Discrete Fourier Analysis, Cauchy Integrals, Construction of Conformal Maps, Univalent Functions (Pure & Applied Mathematics)

Introduction to "Applied and Computational Complex Analysis"

Welcome to the world of Applied and Computational Complex Analysis, a comprehensive exploration of both the theoretical and computational dimensions of complex analysis. This book stands at the intersection of pure mathematics and practical application, targeting both researchers and practitioners who seek to deepen their understanding of this rich mathematical domain. Through a rigorous yet accessible approach, I aim to provide a thorough discussion on key topics such as Discrete Fourier Analysis, Cauchy Integrals, Conformal Mapping, and the theory of Univalent Functions. Whether you are an academic, a student, or an applied scientist, this book provides a balanced foundation and cutting-edge tools for solving real-world problems in engineering, physics, and computational sciences.

Detailed Summary of the Book

Applied and Computational Complex Analysis delves deeply into the foundational principles of complex analysis while demonstrating its relevance to computational and applied settings. The book takes a step-by-step approach, starting with fundamental concepts such as analytic functions, complex differentiation, and integration via the Cauchy integral and moving toward advanced computational techniques.

One of the central themes of the book is the study of Discrete Fourier Analysis, a cornerstone of modern computational mathematics. I explore how this tool transforms signals and functions into their frequency components, thereby making it indispensable in fields such as image processing, communications, and acoustics. Additionally, special attention is given to the construction and practical applications of conformal maps, a technique extensively used in fluid mechanics, engineering design, and more.

The journey continues with an in-depth discussion of Cauchy integrals, techniques for evaluating complex integrals, and their implications in solving boundary value problems. Furthermore, the book emphasizes univalent functions, exploring their geometric properties and applications in areas such as geometric function theory and complex dynamical systems. My objective throughout is to bridge rigorous mathematics with computational ease, ensuring relevance to practical applications.
