ANU Futures Workshop: Recent Progress of Harmonic Analysis in General Relativity and Quantum Information.
A workshop introducing researchers with some background in harmonic analysis and dispersive partial differential equations to some open problems in general relativity and quantum information.
About
About
Recently, there have been some remarkable breakthroughs of harmonic analysis techniques in general relativity and quantum information.
As some featured examples, we refer to a result in 2021 of Hintz and Vasy and now in 2025 of Hintz, Petersen, and Vasy, in proving global nonlinear stability of Kerr-de Sitter spacetimes, extending Fourier-harmonic analytic methods into nonlinear geometric PDES, and the solution of the L2 curvature conjecture for the Einstein Equations by Klainerman, Rodnianski, and Szeftel.
Some main themes of this workshop will be to explore:
- How harmonic analysis can be used in General Relativity settings, which often involve obstacles like a lack of global Fourier transforms, noncompactness of Lorentzian manifolds and the associated scattering theory, and nonlinear and geometric structure of PDEs.
- The analysis of Schrodinger operators that arise in quantum computing (including themes such as Lieb-Robinson bounds).
One of the main goals of the workshop will be to introduce researchers with some background in harmonic analysis and dispersive PDE to some open and accessible problems in general relativity and quantum information. The structure of the workshop will accommodate time for plenary talks, problem sessions, and discussion and collaboration time. Thus the workshop is ideal for researchers in harmonic analysis or dispersive PDE seeking an introduction to how these techniques may be applied in a general relativity or quantum information setting, and to be acquainted with some accessible open problems in those fields, or conversely researchers in General Relativity or Quantum Information seeking to incorporate more harmonic analysis techniques into their research.
Participation is in person only. There will be talks that are delivered by video link.
