Course 414 - Complex Analysis 2001-02 (Optional JS & SS Mathematics, SS Two-subject Moderatorship )
Lecturer: Dr. Richard M. Timoney
Requirements/prerequisites: 221

Duration: 21 weeks.

Number of lectures per week: 3

Assessment: Regular assignments.

End-of-year Examination: One 3-hour examination

Description: This syllabus is provisional. A revised one is planned which may deal with iteration of polynomial functions.

1. 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.

2. Logarithms, simple connectedness and antiderivatives.

3. Identity theorem for analytic functions, maximum modulus theorem.

4. Open mapping theorem, argument principle, inverses of analytic functions and Rouché's theorem. Removable singularities, Casorati-Weierstrass theorem, Residue theorem.

5. Metric space structures on H(G) and C(G). Boundedness and compactness in H(G).

6. Normal families; metric space structure of M(G).

7. Continuous linear operators and dual spaces. Hahn-Banach theorem (without proof) and applications. Runge's theorem.

8. Hurwitz's theorem, the Schwarz lemma, the Riemann mapping theorem.

Further detailed information about the course will become available via the web site for the course at http://www.maths.tcd.ie/~richardt/414

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.
