Breathing and moving vesicles in a geometric mechanochemical model
Alexander Meiners, Hannes Uecker
We consider a geometric mechanochemical model of vesicles which couples the Helfrich flow for the shape of a lipid bilayer vesicle membrane with a reaction-diffusion equations…

Helfrich cylinders -- instabilities, bifurcations and amplitude equations
Alexander Meiners, Hannes Uecker
Combining local bifurcation analysis with numerical continuation and bifurcation methods we study bifurcations from cylindrical vesicles described by the Helfrich equation with vol…
