COURSE OUTLINE
1. Brief review of complex analysis: Cauchy theorem and integral formula, power series, Cauchy-Riemann equations, harmonic functions. Residue calculus. Argument principle. (Chapters 1, 2, 3 of [SS].)
2. Homotopy of paths, the fundamental group. The fundamental group of punctured complex plane, the winding number and the integral of 1/z. (Chapter 3, Appendix B of [SS].)
3. Analytic continuation and multi-valued analytic functions. The monodromy principle. (Chapter 6 of [MH].) Riemann surfaces: A 1-dimensional complex manifold defined via an atlas of charts. Examples: the Riemann sphere, Riemann surfaces of multi-valued algebraic and analytic functions. Covering spaces and the universal cover. (Chapter 1 of [M]. Chapter 16, Section 7 of [G].)
4. Conformal mappings. Examples. Reflection Principle. (Chapter 2, Section 5.4 of [SS].) Schwarz lemma. Normal families. Riemann mapping theorem. (Chapter 8, Sections 1, 2, 3 of [SS].) Classification of Riemann surfaces (without proof). (Chapter 16 of [G].)
5. Entire functions. Weierstrass and Hadamard product theorems. (Chapter 7 of [SS].)
6. Special functions. Gamma and zeta functions. Connections with the prime number theorem (sketch of the proof). (Chapters 6, 7 of [SS].)
7. Elliptic functions. Weierstrass P-function. (Chapter 8 of [SS].) Interpretation of elliptic functions as meromorphic functions on the torus. (Chapter 5 of [FB].)
