Rigorous Analysis and Dynamics of Hibler's sea ice model
Felix Brandt, Karoline Disser, Robert Haller-Dintelmann +1
This article develops for the first time a rigorous analysis of Hibler's model of sea ice dynamics. Identifying Hibler's ice stress as a quasilinear second order operator and regar…
Hardy's inequality for functions vanishing on a part of the boundary
Moritz Egert, Robert Haller-Dintelmann, Joachim Rehberg
We develop a geometric framework for Hardy's inequality on a bounded domain when the functions do vanish only on a closed portion of the boundary.
Elliptic and parabolic reguarity for second order divergence operators with mixed boundary conditions
Robert Haller-Dintelmann, Alf Jonsson, Dorothee Knees +1
We study second order equations and systems on non-Lipschitz domains including mixed boundary conditions. The key result is interpolation for suitable function spaces. From this, e…
Energy flow above the threshold of tunnel effect
Felix Ali Mehmeti, Robert Haller-Dintelmann, Virginie Régnier
We consider the Klein-Gordon equation on two half-axes connected at their origins. We add a potential that is constant but different on each branch. In a previous paper, we studied…
The Influence of the Tunnel Effect on L-infinity-time decay
Felix Ali Mehmeti, Robert Haller-Dintelmann, Virginie Régnier
We consider the Klein-Gordon equation on a star-shaped network composed of n half-axes connected at their origins. We add a potential which is constant but different on each branch…
Multiple tunnel effect for dispersive waves on a star-shaped network: an explicit formula for the spectral representation
Felix Ali Mehmeti, Robert Haller-Dintelmann, Virginie Régnier
We consider the Klein-Gordon equation on a star-shaped network composed of n half-axes connected at their origins. We add a potential which is constant but different on each branch…
