Inertial Manifolds for the Hyperbolic Cahn-Hilliard Equation
Ahmed Bonfoh
2:30pm|Simonyi Hall 101 and Remote Access

An inertial manifold is a positively invariant smooth finite-dimensional manifold which contains the global attractor and which attracts the trajectories at a uniform exponential rate. It follows that the infinite-dimensional dynamical system is...

Two or infinity
Dan Cristofaro-Gardiner
9:15am|Remote Access

It is conjectured that every Reeb flow on a closed three-manifold has either two, or infinitely many, simple periodic orbits. I will survey what is currently known about this conjecture. Then, I will try to explain some of the key ideas behind...

Higher Order Fourier Uniformity of Bounded Multiplicative Functions in Short Intervals
Terence Tao
4:30pm|Princeton University McDonnell A02

Abstract: The Higher order Fourier uniformity conjecture asserts that on most short intervals, the Mobius function is asymptotically uniform in the sense of Gowers; in particular, its normalized Fourier coefficients decay to zero.  This conjecture...

Random Lattices with Symmetries
Maryna Viazovska
2:30pm|Princeton University McDonnell A02

Abstract: What is the densest lattice sphere packing in the d-dimensional Euclidean space? In this talk we will investigate this question as dimension d goes to infinity and we will focus on the lower bounds for the best packing density, or in other...

Rigidity of Kleinian Groups and Zariski Density in Higher Rank
Hee Oh
11:30am|Princeton University McDonnell A02

Abstract: Discrete subgroups of PSL(2,C) are called Kleinian groups and they are fundamental groups of complete oriented hyperbolic 3-manifolds/orbifolds. Except for countably many conjugacy classes, all Kleinian groups have infinite co-volume in...

Sign Patterns of the Mobius Function
Tamar Ziegler
10:00am|Princeton University McDonnell A02

Abstract: The Mobius function is one of the most important arithmetic functions. There is a vague yet well known principle regarding its randomness properties called the “Mobius randomness law". It basically states that the Mobius function should be...

Global Well-Posedness of Stochastic Abelian-Higgs in Two Dimensions
Sky Cao
2:30pm|Simonyi Hall 101 and Remote Access

There has been much recent progress on the local solution theory for geometric singular SPDEs. However, the global theory is still largely open. In my talk, I will discuss the global well-posedness of the stochastic Abelian-Higgs model in two...

Toric and Semitoric Symplectic Geometry: Progress and Challenges
Álvaro Pelayo
9:15am|Remote Access

Toric integrable systems, also known as symplectic toric manifolds, arise as examples in different contexts within geometry and related areas. Semitoric integrable systems are a generalization of toric integrable systems in dimension four. In this...

Continuous Symmetry Breaking: A Rigorous Approach
Sara Daneri
2:30pm|Simonyi Hall 101 and Remote Access

At the base of spontaneous pattern formation is universally believed to be the competition between short range attractive and long range repulsive forces. Though such a phenomenon is observed in experiments and simulations, a rigorous understanding...
