Weil-Petersson geometry, Dehn filling and branched surfaces

We study pseudo-Anosov mapping classes with bounded normalized Weil-Petersson translation distance (and unbounded genus). In analogy with a result of Farb-Leininger-Margalit for Teichmuller translation distances, we show all such mapping classes fit together into a finite collection of cusped hyperbolic 3-manifolds, where the cusps are filled to become either vertical (transverse to fibers) or horizontal (parallel to fibers). After a reduction using work of Schlenker, Kojima-McShane and Brock-Bromberg, the argument uses the theory of branched surfaces in 3-manifolds. This is joint work with Chris Leininger, Juan Souto and Sam Taylor.

On the inhomogeneity of the Mandelbrot set

We will show that the Mandelbrot set is totally locally conformally inhomogeneous: the only orientation preserving conformal map $f:U → V$ with $U\cap ∂ M \neq \emptyset$ and satisfying $f(U\cap∂ M) ⊂ ∂ M$ is the identity map. The proof uses the study of the local conformal symmetries of the Julia sets: we will show in many cases, the dynamics can be recovered from local conformal structures of the Julia sets.

Limiting Measure of Lee-Yang Zeros for the Cayley Tree

I will explain how to use detailed properties of expanding maps of the circle (Shub-Sullivan rigidity, Ledrappier-Young formula, large deviations principle, ...) to study the limiting distribution of Lee-Yang zeros for the Ising Model on the Cayley Tree. No background in mathematical physics is expected of the audience. This is joint work with Ivan Chio, Caleb He, and Anthony Ji.

A survey of Cannon-Thurston Maps

We shall survey the theory of Cannon-Thurston Maps. These form a connecting link between the hyperbolic geometry and the complex dynamics of Kleinian groups. We shall also discuss a generalization to geometric group theory and end with some open problems.
