: Representation for meromorphic and entire functions, and analytic continuation. Key Features of the Book Foundations of Complex Analysis by S. Ponnusamy | Goodreads
Ponnusamy didn't just give the answer. He showed the contour, the decay estimate, the simple pole at ( z = i ), and the real-part trick. For the first time that night, Arjun didn't feel alone. A mathematician from India, writing in crisp, no-nonsense English, had reached across decades and bandwidth to hold his hand through a singular integral. Taylor series for analytic functions
