Complex analysis is a branch of mathematics that focuses on functions defined on the complex plane, utilizing complex numbers with real and imaginary components. Unlike real analysis, which deals with functions of real variables, complex analysis explores the unique properties of functions dependent on complex numbers. The aim of the book "Complex Analysis" is to provide a comprehensive and accessible exploration of the profound field of complex analysis, elucidating the intricate properties and functions of complex numbers. Authored with clarity and precision, the book seeks to demystify the complexities inherent in this branch of mathematics, making it accessible to a broad audience, including undergraduate and graduate students in mathematics, physics, engineering, and related disciplines.
