Existence and stability of shrinkers for the harmonic map heat flow in higher dimensions

Irfan Glogić, Sarah Kistner, Birgit Schörkhuber

We study singularity formation for the heat flow of harmonic maps from $R^{d}$ . For each $d \geq 4$ , we construct a compact, $d$ -dimensional, rotationally symmetric target manifold…

Co-dimension one stable blowup for the quadratic wave equation beyond the light cone

Po-Ning Chen, Roland Donninger, Irfan Glogić +2

We study the stability of an explicitly known, non-trivial self-similar blowup solution of the quadratic wave equation in the lowest energy supercritical dimension $d = 7$ . This so…

Stable self-similar blowup in the supercritical heat flow of harmonic maps

Paweł Biernat, Roland Donninger, Birgit Schörkhuber

We consider the heat flow of corotational harmonic maps from $R^{3}$ to the three-sphere and prove the nonlinear asymptotic stability of a particular self-similar shrinker th…
