Local existence and uniqueness for the n-dimensional Helfrich flow as a projected gradient flow

Takeyuki NAGASAWA and Taekyung YI

Full-text: Open access


The gradient flow associated to the Helfrich variational problem, called the Helfrich flow is considered. Here the n-dimensional Helfrich flow is investigated for any n, as a projected gradient flow. A result of local existence is proved. The uniqueness is shown for the cases (i) for the initial hypersurface with non-zero Gramian when n ≥ 2, (ii) for every initial curve when n = 1.
