Nonlinear stability of extremal Reissner-Nordström black holes in spherical symmetry
Yannis Angelopoulos, Christoph Kehle, Ryan Unger
In this paper, we prove the codimension-one nonlinear asymptotic stability of the extremal Reissner-Nordström family of black holes in the spherically symmetric Einstein-Maxwell-ne…

Supersonic flow past an airfoil
Yannis Angelopoulos
We consider a supersonic flow past an airfoil in the context of the steady, isentropic and irrotational compressible Euler equations. We show that for appropriate data, either a sh…
