Description: Geometric function theory is a branch of complex analysis that seeks to relate analytic properties of conformal maps to geometric properties of their images. The subject has deep connections with other areas of mathematics such as potential theory, hyperbolic geometry, and dynamical systems. The course aims to introduce students to geometric function theory in a broad sense, and to define concepts and present techniques required in modern applications such as the theory of the Schramm-Loewner evolution.

Content (tentative): Review of conformal mapping, Carathéodory's theorem, Kellogg's theorem, basic potential theory, harmonic measure, extremal length, Beurling's estimates, Plessner and McMillan's theorems, Loewner's equation. Further applications may be treated depending on the audience's interests.

Textbook: J.B. Garnett & D.E. Marshall, Harmonic Measure, New Mathematical Monographs, Cambridge University Press, 2005. (Reprint of the 2005 original) Errata

Further reading: Examination: Homework problems and oral examination.

Prerequisites: Complex Analysis and Advanced Real Analysis I (required); Advanced Real Analysis II and Fourier Analysis (preferred).
