Variational models for the interaction of surfactants with curvature – existence and regularity of minimizers in the case of flexible curves

Abstract We consider a curve with boundary points free to move on a line in $\R^2$, which evolves by the $L^2$--gradient flow of the elastic energy, that is a linear combination of the Willmore and the length functional.For such planar evolution problem we study the short and long--time existence. Once we establish under which boundary conditions the PDE's system is well--posed (in our case the Navier boundary conditions), employing the Solonnikov theory for linear parabolic systems in H\"older space, we show that there exists a unique flow in a maximal time interval $[0,T)$. Then, using energy methods we prove that the maximal time is actually $T= + \infty$. Mathematics Subject Classification (2020): Primary 53E40; 35G31, 35A01.
