The format will be the same as in the year 2019/2020 exam, which can be considered a sample paper.
Credit will be given for the best 3 questions out of total 4 questions.
Organization and Content:
For up-to date information, please see the module page MAU34205-202122 TOPICS IN COMPLEX ANALYSIS I on TCD Blackboard.
To be posted regularly to Blackboard as videos with slides, starting from the first week. I'll be sending respective annoucements through Blackboard at the beginning.
Real and complex differentiability.
Conformal mappings (definition, examples, relation between conformal and holomorphic mappings).
Complex integration of holomorphic functions along arbitrary continuous paths.
Homotopy version of Cauchy's theorem.
Elements of homology and homological version of Cauchy's theorem.
Cauchy-Green's Formula and relation to Cauchy's Integral formula.
Compact convergence and Weierstrass theorem.
Order of zeroes. The identity principle.
Isolated singularities. Removable singularities, poles, essential singularities.
Riemann extension theorem.
Meromorphic functions. Casorati-Weierstrass theorem.
The argument principle. Rouché's theorem. Open mapping theorem.
The univalence theorem (local injectivity criterion). Inverse maping theorem.

The following book of Fulton is quite remarkable in that it includes many topological and homological aspects of Complex Analysis
on a deeper but still elementary level:

My blog post How to give a Mini-talk in Mathematics
All topics around Complex Analysis at large are welcome, e.g. please have a look at the
Advanced Complex Analysis by C. McMullen,
where I had highlighted several topics of interest,
pick few topics and try to search web and/or textbooks for it,
then let me know the topic you liked and I will provide more sources if needed.
