Description:
- Review of the definition of analytic functions, the Cauchy-Riemann
equations, differentiation of power series, and contour integrals.
Various forms of Cauchy's theorem and the Cauchy integral formula;
winding numbers and homotopy.
- Logarithms,
simple connectedness and antiderivatives.
- Identity theorem for analytic functions, maximum modulus theorem.
- Open mapping theorem, argument principle, inverses of
analytic functions and Rouché's theorem. Removable
singularities, Casorati-Weierstrass theorem, Residue
theorem.
- Metric space structures on H(G) and C(G).
Boundedness and compactness in H(G).
- Normal families; metric space structure of M(G).
- Continuous linear operators and dual spaces.
Hahn-Banach theorem (without proof) and applications.
Runge's theorem.
- Hurwitz's theorem, the Schwarz lemma, the Riemann mapping theorem.
Objectives:
This course will build on material covered in 221.
Initially it will cover some familiar material in
greater detail and then continue on to cover basic material in
complex analysis. Some functional analytic techniques will be
developed and applied to prove results in complex analysis.
