Strong stability and the Schiffer Conjecture for the fluid-elastic semigroup
Karoline Disser
In a series of papers, Avalos and Triggiani established the fluid-elastic semigroup for the coupled Stokes-Lamé system modelling the coupled dynamics of a linearly elastic structu…

Global existence and uniqueness for Hibler's visco-plastic sea-ice model
Stefan Dingel, Karoline Disser
In this paper, we prove global existence and uniqueness of weak solutions to the momentum equations of Hibler's visco-plastic model for the dynamics of the arctic sea-ice covers. A…

Global existence and convergence to pressure waves in nonlinear fluid-structure interaction
Karoline Disser, Michelle Luckas
We consider a non-linear system modelling the dynamics of a linearly elastic body immersed in an incompressible viscous fluid, without damping on the elastic part. We prove local e…
