Online Seminar on Algebraic and Complex Dynamics


Description

Welcome to the Online Seminar on Algebraic and Complex Dynamics.

This seminar centered loosely around algebraic dynamics, complex dynamics, and related topics. We meet weekly for a 90-minute talk, with the first 30 minutes aiming towards non-experts and graduate students. After the talk we will have 30 minutes of informal discussion.

The seminar usually takes place on Tuesdays, either at 9am in Beijing/Taipei (= UTC 1am) or at 3pm in Beijing/Taipei (= UTC 7am), depending on where the speakers are located. The talks will be hosted on Zoom. All are welcome to tune in.

Title: Boundedness problems in conformal dynamics

Abstract: In 1980s, Thurston’s formulated the geometrization conjecture for 3-manifolds, and proved the hyperbolization theorem. The keys to Thurston’s proof are two bounded results for certain deformation spaces of Kleinian groups. In early 1990s, motivated by Thurston’s boundedness theorem and the Sullivan dictionary, McMullen conjectured that certain hyperbolic components of rational maps are bounded.
In this talk, I will start with a historical discussion on a general strategy of the proof of Thurston’s boundedness theorem. I will then explain how a similar strategy could work for rational maps, and discuss some recent breakthrough towards McMullen's boundedness conjecture.
