Small deformations of a near cylindrical tube for the Canham-Helfrich Energy with applications to biological membranes

Charles M. Elliott, Carsten Gräser, Philip J. Herbert

In this article we develop a quadratic energy which approximates the Canham-Helfrich energy for a tube-like surface with clamped boundary and area constraint. The energy is suited…

An iterative approach to a fluid-rigid body interaction problem

Charles M. Elliott, Thomas Sales

We study a novel approach for the existence of solutions to an incompressible fluid-rigid body interaction problem in three dimensions. Our approach introduces an iteration based o…

An evolving surface finite element method for the Cahn-Hilliard equation with a logarithmic potential

Charles M. Elliott, Thomas Sales

In this paper we study semi-discrete and fully discrete evolving surface finite element schemes for the Cahn-Hilliard equation with a logarithmic potential. Specifically we conside…

The evolving surface Cahn-Hilliard equation with a degenerate mobility

Charles M. Elliott, Thomas Sales

We consider the existence of suitable weak solutions to the Cahn-Hilliard equation with a non-constant (degenerate) mobility on a class of evolving surfaces. We also show weak-stro…

A fully discrete evolving surface finite element method for the Cahn-Hilliard equation with a regular potential

Charles M. Elliott, Thomas Sales

We study two fully discrete evolving surface finite element schemes for the Cahn-Hilliard equation on an evolving surface, given a smooth potential with polynomial growth. In parti…
