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.


Speaker

I am a Milnor Lecturer at IMS, Stony Brook University. I was a postdoc assistant professor at University of Michigan, Ann Arbor. I got my PhD from Harvard University in 2019, advised by Curtis McMullen.

My research is in dynamics and geometry, especially the dynamics of rational maps on the Riemann sphere, the corresponding moduli space, and its interplays with Kleinian groups, hyperbolic geometry, Teichmuller theory and Berkovich dynamics.

  • Vertex operator algebras, conformal blocks, and tensor categories

    课程描述 DescriptionVertex operator algebras (VOAs) are mathematical objects describing 2d chiral conformal field theory. The representation category of a “strongly rational” VOA is a modular tensor category (which yields a 3d topological quantum field theory), and conjecturally, all modular tensor categories arise from such VOA representations. Conformal blocks are the crucial ingredients in...

  • Topics in Inverse Problems

    Note: Due to the COVID-19,the course will be delivered online from May 9. 课程描述 DescriptionInverse problem refers to a kind of problem of inverting the physical parameters and geometric features of the interested area by the measured data, and is an important subject for the intersection of industrial and applied mathematics. It consists of many areas including modeling, partial differenti...
