MA205: Complex Analysis

Undergraduate course, Mathematics Department, IIT Bombay, 2021

This is an introductory course in Complex Analysis for undergraduates in their sophomore year.

I was a TA for the Autumn 2021 offering of this course under Professor Sudarshan Gurjar. The course covers the following.

  • Holomorphic and analytic functions.
  • Cauchy-Riemann equations and harmonic functions.
  • Power series and their convergence via the root test and ratio test.
  • The exponential, sine, and cosine functions.
  • Zeroes and poles of analytic functions.
  • Cauchy’s Theorem and Cauchy’s Integral Formula.
  • The complex logarithm and singularities.
  • Laurent Series and Cauchy’s Residue Theorem.
  • Evaluating Real Integrals via Cauchy’s Residue Theorem.
  • Some exotic results including but not limited to Liouville’s Theorem, Casorati-Weierstrass Theorem, Argument Principle, Rouché’s Theorem, the Little and Big Picard Theorems.
  • Conformal mappings.
