The elliptic Einstein-DeTurck equation may be used to numerically find Einstein metrics on Riemannian manifolds.
- Static Lorentzian Einstein metrics are considered by analytically continuing to Euclidean time.
- Ricci-DeTurck flow is a constructive algorithm to solve this equation, and is simple to implement when the solution is a stable fixed point, the only complication being that Ricci solitons may exist which are not Einstein.
- Here we extend previous work to consider the Einstein-DeTurck equation for Riemannian manifolds with boundaries, and those that continue to static Lorentzian spacetimes which are asymptotically flat, Kaluza-Klein, locally AdS or have extremal horizons.
