Weakly turbulent dynamics on Schwarzschild-AdS black hole spacetimes
Christoph Kehle, Georgios Moschidis
In the presence of confinement, small-data solutions to nonlinear dispersive equations can exhibit a gradual energy transfer from low to high frequencies, a mechanism driving the e…

On well-posedness for the timelike minimal surface equation
Georgios Moschidis, Igor Rodnianski
We obtain improved local well-posedness results for the Lorentzian timelike minimal surface equation. In dimension , for a surface of arbitrary co-dimension, we show a gain of…

On the non-existence of trapped surfaces under low-regularity bounds
Jonathan Luk, Georgios Moschidis
The emergence of trapped surfaces in solutions to the Einstein field equations is intimately tied to the well-posedness properties of the corresponding Cauchy problem in the low re…
