Asymptotic stability of local Helfrich minimizers

Daniel Lengeler[1]

(1) Universität Regensburg, Germany

We show that local minimizers of the Canham–Helfrich energy are asymptotically stable with respect to a model for relaxational fluid vesicle dynamics that we already studied in previous papers ([13, 14]). The proof is based on a Łojasiewicz–Simon inequality.
