Instability of anchored spirals in geometric flows
Anthony Cortez, Nan Li, Nathan Mihm +3
We investigate existence, stability, and instability of anchored rotating spiral waves in a model for geometric curve evolution. We find existence in a parameter regime limiting on…

Anchored spirals in the driven curvature flow approximation
Nan Li, Arnd Scheel
We study existence, asymptotics, and stability of spiral waves in a driven curvature approximation, supplemented with an anchoring condition on a circle of finite radius. We analyz…
