From Niels Bohr to Schrödinger: The Hyperboloidal Workshop Strikes Back in Vienna

Hyperboloidal Foliations and their Applications, held at the Erwin Schrödinger Institute in Vienna, brought together researchers from geometric analysis, mathematical & numerical relativity, as well as gravitational-wave physics to explore the theory and impact of hyperboloidal methods. Following the grounding 2023 workshop Infinity on a Gridshell, organized by the Strong Group at the Niels Bohr Institute, the meeting highlighted recent advances in black hole perturbation theory, gravitational self-force, and the nonlinear numerical evolution of asymptotically flat spacetimes. Particular attention was given to how hyperboloidal foliations enable a direct and geometrically natural treatment of radiation at null infinity, with implications across the inspiral, merger, and ringdown phases of compact binary coalescence.

The workshop was organized by Rodrigo Panosso Macedo alongside external collaborators and featured the participation from Center of Gravity members Marina Minucci and Ariadna Ribes Metidier, as well as former member Marina de Amicis. The lively discussions and cross-disciplinary exchanges underscored the growing role of hyperboloidal methods in gravity as a unifying framework for analytical and numerical approaches to wave propagation in dynamical spacetimes.
