Do not just read the transformations; sketch the domain and its image on paper to build spatial intuition.
The book’s true value is reflected in the feedback from the academic community. On Flipkart, the book has earned an excellent rating of 4.4 stars from over 440 user reviews, with many praising its utility for high-level exam preparation and rigorous studies. The feedback can be summarized as:
: Saminathan Ponnusamy, a professor at the Indian Institute of Technology, Madras.
Hundreds of worked examples and exercises challenge students to apply theoretical proofs to concrete problems. foundation of complex analysis by ponnusamy pdf top
Additionally, the book is a valuable supplementary resource. A syllabus from Amrita Vishwa Vidyapeetham lists it as a primary reference for courses in Complex Analysis and Numerical Methods, covering topics like the Cauchy-Riemann equations and the Cauchy Residue Theorem.
The textbook addresses the critical interdependence between real and complex variables. It avoids isolating complex analysis as an abstract anomaly, instead developing it as a natural, highly structured extension of real calculus.
: Each chapter includes well-structured examples and exercises with hints and solution outlines to aid self-study. Do not just read the transformations; sketch the
: Chapters begin with Complex Numbers (geometric interpretation and topology of the complex plane), followed by Functions, Limit, and Continuity (including stereographic projection).
: Many sections are designed to be less interdependent, allowing instructors to customize the course content easily. Educational Context

Beyond the fundamentals, Ponnusamy introduces advanced geometric and analytical tools used in modern research:
Pay close attention to the regions of convergence, as understanding where a series fails to converge is the secret to mastering singularities.

This section highlights the geometric beauty of the subject. It details how complex functions preserve angles, focusing heavily on (bilinear transformations) and their ability to map circles and lines to other circles and lines. 4. Complex Integration and Cauchy's Theorem
Before diving into calculus, the book establishes the algebraic, geometric, and topological properties of complex numbers. You will master the topology of the complex plane, including open, closed, connected, and compact sets. 2. Analytic and Harmonic Functions
