The Birch and Swinnerton-Dyer Conjecture and Related Problems: Recent Results

Birch and Swinnerton-Dyer proposed their remarkable conjecture linking the arithmetic of an elliptic curve with analytic properties of its L-function over 60 years ago. It has been just over 25 years since the BSD conjecture was listed as one of the Clay Mathematics Institute’s Millennium Prize Problems. This workshop will focus on some of the recent results towards the conjecture and related problems, including generalizations to abelian varieties, questions about ranks, computational work, results over function fields, and arithmetic statistics.

Multi-valued Harmonicity

Harmonic functions which are not single-valued arise in classical complex function theory, but these objects have emerged in several different places in more recent research.  Already 50 years ago, Almgren studied the calculus of multi-valued functions in general dimensions as a means to parametrize area-minimizing submanifolds of codimension greater than one, and modern regularity theory in that subject employs this framework as a basic tool. 

More recently, multi-valued harmonic 1-forms and spinors have appeared as limiting blowup profiles for certain new gauge theories with nonimpact gauge group, and in addition when characterising degenerations of calibrated submanifolds in Riemannian manifolds with special holonomy.

More recently still, multi-valued harmonicity arises in the context of thin obstacle problems. The new (and perhaps central) features of these objects are their codimension two branching sets, which are the root of many analytic subtleties. There are now many researchers encountering these objects and proving interesting theorems about multi-valued harmonic objects.

This workshop aims to collect experts from these various branches of geometric analysis to illuminate problems and methods that should be useful to the whole community, and to suggest new directions in the field.

Water Waves and Related Fluid Models

The aim of this workshop is to discuss recent developments in the theory of water waves and related fluid models.  The main topics to be discussed are: local and global regularity, dynamical formation of singularities, and numerical methods.

In the past five years, new methods have emerged in the study of global solutions of quasilinear evolutions, inspired by the advances in semilinear theory.  The basic idea is to combine the classical energy and vector-fields methods with a new ingredient, namely refined analysis of the Duhamel formula using the Fourier transform method.  These new methods led to major progress in understanding the global dynamics of small-data solutions of many physically relevent Quasilinear models in 3 and 2 dimensions, including the construction of the first nontrivial global solutions in several classical water wave models.  At the same time, new methods have been developed to study the dynamics of large-data solutions, and the formation of certain types of interface singularities, such as the so-called splash singularity, wherein a locally smooth interface self-intersects in finite time.  The workshop will survey these recent developments and future research directions.

Speakers: Thomas Alazard (ENS), Peter Constantin (Princeton), Diego Cordoba (ICMAT), Daniel Coutand (Heriot Watt), Charles Fefferman (Princeton), Javier Gomez Serrano (Princeton), Alex Ionescu (Princeton), Alex Kiselev (Rice), David Lannes (Bordeaux), Victor Lie (Purdue), Nader Masmoudi (Courant), Benoit Pausader (Princeton), Fabio Pusateri (Princeton), Gregory Seregin (Oxford), Jalal Shatah (Courant), Steve Shkoller (UC Davis), Chongchun Zeng (Georgia Tech)

The P=W Conjecture in Non Abelian Hodge Theory

The P=W Conjecture in the Non Abelian Hodge Theory of compact Riemann surfaces and for the general complex linear group was formulated by M.A. de Cataldo, T. Hausel and L. Migliorini in 2008. It was proved in the special cases of rank 2 and subsequently of genus 2. It has been proved in all rank and genera in 2022 by two independent teams. The conjecture is still open for other complex reductive groups and for higher dimensional complex projective manifolds. Since its inception, the conjecture has inspired and motivated work in several related areas: Non Abelian Hodge Theory (also in positive and mixed characteristics) such as Hitchin systems and character varieties, mirror symmetry, hyperkahler geometry, geometric representation theory, Donaldson-Thomas invariants, cluster varieties.

This workshop aims at bringing together experts in these related areas with the purpose of bringing into focus the state of the art in the subject, sharpening the vision for the near future and laying the ground for new collaborations. 

Speakers: Ben Davison (Edinburgh), Camilla Felisetti (Modena and Reggio Emilia), Andres Fernandez Herrero (Penn), Andrew Harder (Lehigh), Victoria Hoskins (Radboud), Tasuki Kinjo (Kyoto), Emmanuel Letellier (Jussieu), Anton Mellit (Vienna), Tony Pantev (Penn), Fernando Rodriguez Villegas (ICTP), Olivier Schiffmann (Paris-Saclay), Junliang Shen (Yale), Olga Trapeznikova (IST), Qizheng Yin (Peking), Siqing Zhang (IAS), Zili Zhang (Tongji)

Number Theory and Physics

This workshop will explore the interactions between number theory and physics, specifically focussing on four main points of contact:

  • L-function, Random Matrix Theory and Quantum Chaos 
  • Number Theory, Representation Theory and Donaldson-Thomas invariants
  • Feynman diagrams and multi-zeta values
  • The Geometric and Arithmetic Langlands Program

These topics, of current interest and activity, share a significant intersection with both number theory and physics and strongly influence and enrich one another. 

Each morning an expository talk will address one of these topics. The talks will be broad and expository, with an emphasis on the underlying theme of the workshop: the interplay between number theory and physics. Speakers are encouraged to include bold speculations and their vision for the future of the subject. The afternoon sessions will be devoted to more specialised talks.

The goal of the workshop is to bring together the four strands of the interaction between number theory and physics so that experts and scientists in general can glimpse the larger picture.

Speakers:  Manjul Bhargava (Princeton), Gaetan Borot (Geneve), Francis Brown (Jussieu), Philip Candelas (Oxford)), Sergei Gukov (Caltech), Andrew Hodges (Oxford), Jon Keating (Bristol), Maxim Kontsevich (IHES), Dirk Kreimer (Humboldt), Gérard Laumon (d’Orsay), Andrei Okounkov (Columbia), Marcus Reineke (Wuppertal), Zeev Rudnick (Tel Aviv), Edward Witten (IAS)

This is one of four concurrent workshops held in association with the 2013 Clay Research Conference.
