Aula Seminari - Department of Mathematics, University of Pisa
The talk will be devoted to phase-field approximations of the Willmore functional and the associated L2-flow. After introducing the various approximations that have been proposed in the literature, I will discuss the asymptotic behavior of the associated flows, and the connection with the continuous Willmore flow. A convergent scheme will be proposed for simulating two of these flows, and their behavior will be illustrated on 2D and 3D examples, in both smooth and singular situations.
