Semialgebraic sets and the Kakeya Problem

In joint work with Keith Rogers, we study the connection between the Kakeya problem and the highlights of the theory of semialgebraic sets such as Tarski's projection theorem and Gromov's algebraic lemma.

Finding nondisplaceable Lagrangian tori via toric degeneration.

Starting with a semi-Fano toric surface, I will explain how to find families of Lagrangian tori with nontrivial deformed Floer cohomology. The proof uses toric degeneration method to compute the potential functions of these tori.

Prime orbit theorems for expanding Thurston maps

Analogues of the Riemann zeta function were first introduced into geometry by A. Selberg and into dynamics by M. Artin, B. Mazur, and S. Smale. Analytic studies of such dynamical zeta functions yield quantitative information on the distribution of closed geodesics and periodic orbits.

We obtain the first Prime Orbit Theorem, as an analogue of the Prime Number Theorem, in complex dynamics outside of hyperbolic maps, for a class of branched covering maps on the $2$-sphere called expanding Thurston maps $f$. More precisely, we show that the number of primitive periodic orbits of $f$, ordered by a weight on each point induced by a non-constant real-valued Hölder continuous function on $S^2$ satisfying some additional regularity conditions, is asymptotically the same as the well-known logarithmic integral, with an exponentially small error term. Such a result follows from our quantitative study of the holomorphic extension properties of the associated dynamical zeta functions and dynamical Dirichlet series.

In particular, the above result applies to postcritically-finite rational maps whose Julia set is the whole Riemann sphere. Moreover, we prove that the regularity conditions needed here are generic; and for a Lattès map $f$, a continuously differentiable function satisfies such a condition if and only if it is not cohomologous to a constant. This is a joint work with T. Zheng.

Canonical models, minimal models and their singularities

In this talk we will run with the definitions of canonical and terminal singularities from last week and use them to give definitions of canonical and minimal models of (quasi-)projective varieties. As usual we will turn to examples to motivate the main ideas.

Scalar curvature as a moment map

In this talk, I will begin by briefly describing what was know about the existence problem for cscK metric prior to Donaldson's work. I will then move on to discuss the Kempf-Ness theorem in the finite-dimensional setting, and how the concepts involved can be understood in the cscK case, by describing the formulation of scalar curvature as a moment map. Time permitting, I will also describe the (conjectural) associated algebraic notion of stablity (K-stability) in the case of polarized algebraic varietes, and recent developments in the subject.

Minimal nonuniquely ergodic foliations on surfaces: II

Measured foliations (laminations) on surfaces are well-known examples of dynamical systems in low dimension. The first return maps of measured foliations are interval exchange transformations which have been studied extensively. Measured foliations also determine the trajectories of Teichmüller and Weil-Petersson geodesics in the Teichmüller space.

In this mini-course, I outline my joint work with Brock, Leininger and Rafi about construction of minimal nonuniquely ergodic laminations. This work was inspired by a construction of Gabai and the earlier work of Lenzhen-Leininger-Rafi where laminations are realized as the limits of sequences of curves on surfaces. An advantage of our method is explicit estimates for intersection numbers of the curves in sequences and the associated subsurface coefficients. These estimates are crucial to control the behavior of geodesics and determine their limit sets in the Thurston compactification of Teichmüller space (which won't be discussed in the minicourse).

Arithmetic, algebraic, and analytic hyperbolicity

In the first part of this talk we will discuss different notions of hyperbolicity for algebraic varieties which are conjecturally related by conjectures of
Green-Griffiths, Lang, and Vojta. Then, we introduce an "analytic" notion of hyperbolicity, which interpolates between being Brody hyperbolic and
hyperbolically embedabble. I hope to give a survey of several known results in the first part. In the second part I will focus on arithmetic questions. For instance, Scholl proved that the
moduli of del Pezzo surfaces is arithmetically hyperbolic. In joint work with Daniel Loughran, we investigate the analogous question for Fano threefolds. For instance, we show that the
moduli of Fano threefolds is not arithmetically hyperbolic, by (explicitly) constructing an abelian surface which sits inside this moduli.
