Existence and convergence of the area-constrained elastic flow

Florian Hauser, Christian Scharrer, Alexander West

We study the evolution of plane closed curves with fixed area moving by the negative $L^{2}$ -gradient of their elastic energy. For smooth initial data, we establish local and global…

Bubble classification of immersions at the boundary of the moduli space with $8 π$ Willmore energy

Christian Scharrer, Manuel Schlierf, Alexander West

We study the asymptotic bubbling behavior of sequences of weak genus- $p$ immersions with diverging conformal classes and limiting Willmore energy of $8 π$ . After applying suitable M…
