New insights into gauge freedom and constraints in numerical relativity

Lee Lindblom
Physics, Caltech


Numerical relativity has undergone a revolution during the pasttwo years, with several groups now routinely performing accurate simulationsof binary black hole systems with multiple orbits, mergers, and ringdown ofthe holes to a final single hole equilibrium state. This talk will discusssome of the mathematical developments that made this revolution possible.In particular new insights will be discussed into how the gauge degrees offreedom may be specified in the Einstein equations, and how this changes thebehavior of the constraints of the theory.
