Virtual Math Seminar: Lukas Geyer (MSU) "Classification of critically fixed anti-rational maps"
- Monday, August 24, 2020 from 4:00pm to 5:00pm
- Webex meeting 120 112 3734 . Password "math".
Anti-rational maps are complex conjugates of rational maps, and studying the dynamics of their iterates is a subject closely related to holomorphic dynamics, with intriguing connections to problems in gravitational lensing. In this talk, I will give a complete description of anti-rational maps for which all critical points are fixed, through simple topological models associated with certain planar graphs. I will also indicate how this result yields a partial classification of "maximal" lensing configurations.
This talk will be through Webex.
