Joint IAS/Princeton Arithmetic Geometry Seminar

Intermediate Extension in Arithmetic Statistics
Will Sawin
3:30pm|Fine 322, Princeton University

Davenport-Heilbronn and Bhargava counted cubic, quartic, and quintic fields by first counting a larger set of orbits in some prehomogenous vector space and then sieving out the orbits corresponding to fields. Several mathematicians have studied...

Members' Colloquium

Convergence of Unitary Representations and Spectral Gaps of Manifolds
2:00pm|Simonyi 101 and Remote Access

Let G be an infinite discrete group. Finite dimensional unitary representations of G are usually quite hard to understand. However, there are interesting notions of convergence of such representations as the dimension tends to infinity. One notion —...

Symplectic Geometry Seminar

Taut Foliations Through a Contact Lens
Thomas Massoni
12:30pm|Simonyi 101 and Remote Access

In the late '90s, Eliashberg and Thurston established a remarkable connection between foliations and contact structures in dimension three: any co-oriented, aspherical foliation on a closed, oriented 3-manifold can be approximated by positive and...

Computer Science/Discrete Mathematics Seminar I

The Tree Evaluation Problem: Context and Recent Results
Ian Mertz
11:00am|Simonyi 101 and Remote Access

The Tree Evaluation Problem has emerged in the past decade as a leading candidate for separating logspace from polynomial time. In this talk we will introduce the problem, as well as the context behind its introduction and conjectured hardness. We...

Analysis and Mathematical Physics

Hawking Mass Monotonicity for Initial Data Sets
2:30pm|Simonyi Hall 101 and Remote Access

An interesting feature of General Relativity is the presence of singularities which can occur in even the simplest examples such as the Schwarzschild spacetime. However, in this case the singularity is cloaked behind the event horizon of the black...

Condensed Learning Seminar

Organizational Meeting
2:30pm|Princeton University, Fine Hall 314

The topic of the learning seminar this semester is "Analytic K-theory''. More precisely, the goal is to use condensed mathematics to obtain a notion of quasi-coherent sheaves/complexes in rigid analytic geometry, develop Efimov's approach to K...

Three 20 Minute Research Talks
Johanna Bimmermann , Soham Chanda and Valerio Assenza

  • Johanna Bimmermann :From Magnetically Twisted to Hyperkähler 

    The tangent bundle of a Kähler manifold admits in a neighborhood of the zero section a hyperkähler structure. From a symplectic point of view, this means we have three symplectic...

Joint PU/IAS Number Theory

Manin's Conjecture For Spherical Fano Threefolds
4:30pm|Simonyi 101 and Remote Access

When an algebraic variety over the rational numbers contains infinitely many rational points, we may study their distribution. In particular, for Fano varieties, the asymptotic behavior of the number of rational points of bounded height is predicted...
