On the sharp interface limit of a phase field model for near-spherical two phase biomembranes
Charles M. Elliott, Luke Hatcher, Björn Stinner
We consider sharp interface asymptotics for a phase field model of two phase near spherical biomembranes involving a coupling between the local mean curvature and the local composi…

A surface finite element method for computational modelling of cell blebbing
Björn Stinner, Andreas Dedner, Adam Nixon
Cell blebs are protrusions of the cell membrane and can be instrumental for cell migration. We derive a continuum model for the mechanical and geometrical aspects of the onset of b…
