 Month Agenda

 MondaySeptember 24, 20184:15 PM - 5:15 PM 5-127 Student Differential Geometry SeminarMichael 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.

 TuesdaySeptember 25, 20184:00 PM - 5:30 PM Math Tower P-131 Geometry/Topology SeminarBenjamin McMillan, Stony Brook University Conservation laws and Monge-Ampère parabolic equationsIn 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.

 WednesdaySeptember 26, 20184:00 PM Math Tower 5-127 Analysis Student SeminarYing Hong Tham, Stony Brook University Loewner Chains and the Loewner PDEWe 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.

 WednesdaySeptember 26, 20184:00 PM - 5:30 PM Math Tower P-131 Algebraic geometry seminarAaron Bertram, University of Utah 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.

 ThursdaySeptember 27, 20182:30 PM - 03:30 AM P-131 Analysis SeminarBoris Bukh, Carnegie Mellon University Nearly orthogonal vectorsHow 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.

 ThursdaySeptember 27, 20184:00 PM - 5:00 PM Math Tower P-131 ColloquiumBoris 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.

 FridaySeptember 28, 201812:00 PM - 1:00 PM Math Tower 5-127 Grad / Postdoc Professional Development SeminarChris Bishop and Christian Schnell, Stony Brook University Mini-workshop: Giving short talks, IIThe second part of a "mini-workshop" about giving short talks.

 ThursdayOctober 04, 20185:00 PM SCGP 102 NY General Relativity SeminarSiyuan Lu, Rutgers On a localized Riemannian Penrose inequalityFor 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.

 FridayOctober 12, 20182:30 PM - 3:30 PM Math Tower P-131 Dynamical Systems SeminarAlena Erchenko, Ohio State University Flexibility of Lyapunov exponents on the circle and the torusThere 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).

 FridayOctober 26, 20182:30 PM - 3:30 PM Math Tower P-131 Dynamical Systems SeminarVasiliki Evdoridou, The Open University 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.
