A variational approach to dislocation problems for periodic Schrödinger operators

Rainer Hempel, Martin Kohlmann

As a simple model for lattice defects like grain boundaries in solid state physics we consider potentials which are obtained from a periodic potential on with p…

Geometric aspects of the periodic -Degasperis-Procesi equation

Joachim Escher, Martin Kohlmann, Boris Kolev

We consider the periodic $\muDP$ equation (a modified version of the Degasperis-Procesi equation) as the geodesic flow of a right-invariant affine connection on the Fréche…
