Mode stability of self-similar wave maps without symmetry in higher dimensions

Roland Donninger, Frederick Moscatelli

We consider wave maps from -dimensional Minkowski space into the -sphere. For every , there exists an explicit self-similar solution that exhibits finite time b…

Future stability of large-data wave maps in energy-supercritical dimensions

Andras Bonk, Roland Donninger

We consider energy-supercritical co-rotational wave maps from Minkowski spacetime to the sphere in odd spatial dimensions. The equation admits an explicit co-rotational self-simila…

Blowup stability of wave maps without symmetry

Roland Donninger, Frederick Moscatelli

We study wave maps from -dimensional Minkowski space into the -sphere without any symmetry assumptions. There exists an explicit self-similar blowup solution and we prove…

Self-similar blowup for the cubic Schrödinger equation

Roland Donninger, Birgit Schörkhuber

We give a rigorous proof for the existence of a finite-energy, self-similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer-…

Self-similar blowup for mass supercritical Schrödinger equations

Roland Donninger, Lorenz Lichtnecker

We consider the focusing nonlinear Schrödinger equation in three spatial dimensions with powers close to three and prove the existence of a self-similar solution. This generalizes…

On stable self-similar blowup for corotational wave maps and equivariant Yang-Mills connections

Roland Donninger, Matthias Ostermann

We consider corotational wave maps from Minkowski spacetime into the sphere and the equivariant Yang-Mills equation for all energy-supercritical dimensions. Both models have explic…
