Description of the session

The study of Riemann surfaces and their groups of automorphism groups, dating back to Klein and Wiman, connects deeply with topology, number theory, complex analysis, and combinatorics through mapping class groups and the theory of dessins d’enfants. Recent progress has caused a renaissance in the field in the last few decades. This session highlights new developments in this research area and their applications to other areas of mathematics.

Topics (in no particular order)

• Compact Riemann surfaces and their automorphisms
• Moduli spaces and families of surfaces
• Dessins d’enfant, quasi-platonic surfaces, and Belyi maps
• Klein surfaces, symmetries, and pseudo-real surfaces
• Genus spectra and strong symmetric genus of groups
• Signatures of group actions
• Mapping class groups and their subgroups
• Hyperelliptic and superelliptic surfaces
• Automorphisms of rational maps P^d -> P^d
• Automorphisms of algebraic surfaces
