What does it mean for a partial differential equation (PDE) or system of PDEs to be integrable? Is there a way to measure how “nonintegrable” a model might be? We shall discuss four results in fluid dynamics and gravitation aimed at answering these questions. Our discussion will reveal rich interconnections between nonlinear waves, astrophysics, combinatorics, geometric analysis, and...

Based on the AdS/CFT correspondence, gauge/gravity duality provides a new relation between quantum field theories on flat space and gravity theories.
In addition to its intrinsic interest and its implications for the nature of gravity, this new duality provides a new approach to calculating observables in strongly coupled quantum field theories, for which there is no standard calculation...

In the language of statistical physics, an extremal black hole is a zero temperature system with a huge amount of residual entropy. Understanding which class of counting formulas can account for a large degeneracy will undoubtedly unveil interesting properties of quantum gravity. In this talk I will discuss the application of Siegel modular forms to black hole entropy counting. The role of...
