IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Equivariant Contact Floer Cohomology for Quotient Spaces
Eric Kilgore
9:15am|Remote Access

I will discuss some recent work establishing the orderability of contact manifolds which arise as a quotient of an aspherically fillable manifold by a finite group action which extends (non-freely) to the filling. This generalizes the well known...

Computer Science/Discrete Mathematics Seminar I

Catalytic Tree Evaluation from Matching Vectors
Seyoon Ragavan
11:00am|Simonyi Hall 101 and Remote Access

What is the relative computational power of time and space? Tree evaluation (TreeEval) has become a central problem in understanding this question, especially after its application by Williams (STOC 2025, IAS CSDM seminar 9/23/25) to prove a...

Princeton University Gravity Initiative Seminar

Instabilities of near-extremal black branes
Alex Buchel
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: Extremal horizons (and associated emergent quantum criticality of the corresponding holographic models) receive strong quantum corrections at very low temperatures.  We point out that when such models are embedded in top-down holography...

Members' Colloquium

The Birch and Swinnerton-Dyer Conjecture: An Introduction and Review
Chris Skinner
1:30pm|Simonyi 101 and Remote Access

This talk will recall the Birch--Swinnerton-Dyer Conjecture and describe highlights of the progress towards it, both pre- and post-millennium.  This will largely be a repeat of the speaker's plenary talk from the 2025 Clay Research conference on the...

Joint IAS/PU Arithmetic Geometry

Algebraic de Rham Cohomology in Mixed Characteristic
Marco D'Adezzio
3:30pm|Princeton University, Fine Hall 224

I will discuss new structural properties of the de Rham cohomology of smooth schemes over the ring of Witt vectors. The main technical input is the $F$-gauge structure on crystalline cohomology. First, I will explain the slope obstruction to the...
