Smooth finite time singularity formation without quantization
Istvan Kadar
We revisit the finite time singularity formation of Krieger-Schlag-Tataru [KST09] for the focusing energy critical wave equation in from a geometric singular-ana…
Matching conditions for scattering solutions of scalar wave equations on extremal Reissner-Nordström spacetimes
Yannis Angelopoulos, Istvan Kadar
We study scattering solutions of the linear wave equation on extremal Reissner-Nordström spacetimes, satisfying the following properties: i) attains a prescribed radiation…
Scattering and stability for ODE-type blow-up surfaces for focusing nonlinear wave equations
Istvan Kadar, Warren Li
We study the focusing power nonlinear wave equation with any power, in Minkowski space of any spacetime dimension. We present a complete understanding of the local stability and sc…
A note on exterior stability of isolated singularity formation for nonlinear wave equations
Istvan Kadar, Lionor Kehrberger
We study the stability of the exterior of Type I and Type II singularity formation for the wave maps equation in with and the power nonlinear wave equat…
