4:15 PM - 5:15 PM

Student Differential Geometry Seminar
Michael Albanese, Stony Brook University
Kahler-Einstein metrics.

As discussed last time, a Riemannian manifold has holonomy contained in the unitary group if and only if the metric is Kahler. Unlike the other cases of reduced holonomy, Kahler metrics need not be Einstein; a metric which is both Kähler and Einstein is called a Kahler-Einstein metric.

We will begin by investigating the curvature tensor of a Kahler metric, which will allow us to determine a necessary cohomological condition for the existence of a Kahler-Einstein metric. Then we will show that the Kahler-Einstein condition is equivalent to the complex Monge-Ampere equation.

Benjamin McMillan, Stony Brook University
Conservation laws and Monge-Ampère parabolic equations

In this talk I will describe how the geometry of an arbitrary parabolic second order equation governs the behavior of its conservation laws, and conversely, how the existence of a conservation law puts strong geometric restrictions on a parabolic equation. In particular, the class of Monge-Ampère parabolic equations is very non-generic, but I will nonetheless describe how the only parabolic equations with at least one conservation law are those of Monge-Ampere type.

Loewner Chains and the Loewner PDE

We will define radial Loewner chains, and describe their various convergence and distortion properties using the tools from the previous weeks.

We will also derive the Loewner PDE, and as an application, prove the Bieberbach conjecture for the case n=3.

Stability Conditions on Projective Space.

Gieseker stability uses the Hilbert polynomial of a coherent sheaf divided by its leading coefficient as an "asymptotic" slope function. We propose a family of stability conditions on Castelnuovo-Mumford regular sheaves that use the Hilbert polynomial divided by its derivative as "exact" slopes. We conjecture that this converges to Gieseker stability (it's true in dimensions 1,2,3). This is joint work with Matteo Altavilla and Marin Petkovic, and an application to the classification of Gorenstein rings is joint work with Brooke Ullery.

Boris Bukh, Carnegie Mellon University
Nearly orthogonal vectors

How can d+k vectors in R^d be arranged so that they are as close to orthogonal as possible? We show intimate connection of this problem to the problem of equiangular lines, and to the problem of bounding the first moment of isotropic measures. Using these connections, we pin down the answer precisely for several values of k and establish asymptotics for all k. Joint work with Chris Cox.

Boris Bukh, Carnegie Mellon
Bipartite Turan problem

What is the largest graph not containing a copy of a fixed graph H? This question of Turan from 1941 remains open. The most challenging case is when H is bipartite. This case leads to interesting graph embedding problems on one hand, and mysterious algebro-geometric constructions on the other. In the talk, I will discuss the key problems and recent progress in the area.

Probabilistic aspects of number theory

On a localized Riemannian Penrose inequality

For a bounded manifold with nonnegative scalar curvature, the Brown-York quasi-local mass is nonnegative and equals to 0 iff it's a domain in Euclidean space by fundamental results of Shi and Tam. Moreover, it is shown that the inequality is equivalent to Positive mass theorem.

We consider the general setting that the bounded manifold allows a horizon. We establish a localized Riemannian Penrose inequality and prove that the equality holds iff it's a domain in Schwarzschild manifold. Similar to the Shi-Tam case, the inequality is equivalent to Riemannian Penrose inequality.

This is based on joint works with P. Miao.

Career advice from Lilia Tsalenko

Lilia Tsalenko, http://www.linkedin.com/in/liliamt, has over 25 years of professional experience, with 13+ years as the founder and CEO of Elti Solutions, a Global Talent Search and Recruiting Company. She joined Blockstream in September of 2017, a company pioneering advancements in cryptography and blockchain technology, as Head of Talent Acquisition and is working on scaling the global team over the next year. Before that, Lilia worked for 10+ years as a Software Engineer for many companies in the San Francisco Bay Area.

In the seminar, Lilia is going to talk a little bit about her career path and explain how finding a job in the tech sector looks like from the point of view of a recruiter. She will also draw on her experience to offer career advice for math PhD's.

Flexibility of Lyapunov exponents on the circle and the torus

There are several interesting classes of measures. For two special classes of dynamical systems, we will concentrate on the invariant measure that is absolutely continuous with respect to the Lebesgue measure and the measure of maximal entropy. First, we show that Lyapunov exponents with respect to these two probability measures for smooth expanding circle maps of a fixed degree $≥ 2$ take on all values that satisfy some well-known inequalities. Then, we demonstrate a similar result for positive Lyapunov exponents with respect to these two measures for Anosov area-preserving diffeomorphisms on a two-torus that are homotopic to a fixed area-preserving Anosov automorphism (work in progress).

Singularities of inner functions associated to entire maps in the class $\mathcal{B}$

Let $f$ be a transcendental entire function and $U$ be an unbounded, invariant Fatou component of $f$. We can associate an inner function, $g$ say, to the restriction of $f$ to $U$. We consider two classes of functions in $\mathcal{B}$ having finitely many tracts. We show that if $f$ belongs to either of these two classes the number of singularities of $g$ on the unit circle is equal to the number of tracts of $f$. This is joint work with N. Fagella, X. Jarque and D. Sixsmith.
