A Course in Mathematical Analysis 2-1 (Complex Variable) by Edouard Goursat - PDF

About this book :-
"A Course in Mathematical Analysis Volume 2 Part 1 (FUNCTIONS OF A COMPLEX VARIABLE)" by Édouard Goursat is a classic text in "complex analysis" that has shaped the study of functions of a complex variable for over a century. Designed for advanced undergraduate and graduate students, this volume introduces the rigorous foundation of the subject while maintaining clarity and precision. The book systematically develops key concepts, making it ideal for both learning and reference. The text explores "analytic functions", including their general properties, power series expansions, and the behavior of singularities. Goursat also presents conformal mappings and geometric interpretations, providing readers with intuitive insights alongside formal proofs. Important topics like Laurent series, residues, and applications of "Cauchy’s theorem" are explained in detail, demonstrating the power of these methods in solving complex variable problems. In addition, the book covers multi-valued functions, analytic extension, and the groundwork for elliptic functions. Goursat’s careful treatment ensures a deep understanding of both theory and application, making this work a timeless resource for mathematicians, physicists, and engineers. With its structured approach and rigorous proofs, this volume remains a cornerstone in the study of "complex analysis".
