Some remarks on equivariant elliptic operators and their invariants
Jochen Brüning, Ken Richardson
In this expository article, we consider first order elliptic differential operators acting on smooth vector bundles over compact manifolds, and certain invariants derived from the…
Heat kernel estimates and the relative compactness of perturbations by potentials
Jochen Brüning, Batu Güneysu
We consider a self-adjoint non-negative operator in a Hilbert space . We assume that the semigroup is defined by an integr…
Schrödinger operators on armchair nanotubes. I
Andrey Badanin, Jochen Brüning, Evgeny Korotyaev +1
We consider the Schrödinger operator with a periodic potential on quasi-1D models of armchair single-wall nanotubes. The spectrum of this operator consists of an absolutely continu…
Schrödinger operators on armchair nanotubes. II
Andrey Badanin, Jochen Brüning, Evgeny Korotyaev
We consider the Schrödinger operator with a periodic potential on quasi-1D models of armchair single-wall nanotubes. The spectrum of this operator consists of an absolutely continu…
Regularity and index theory for Dirac-Schrödinger systems with Lipschitz coefficients
Werner Ballmann, Jochen Brüning, Gilles Carron
Dirac-Schrödinger systems play a central role when modeling Dirac bundles and Dirac-Schrödinger operators near the boundary, along ends or near other singularities of Riemannian ma…
Inverse spectral analysis for finite matrix-valued Jacobi operators
Jochen Brüning, Dmitry Chelkak, Evgeny Korotyaev
Consider the Jacobi operators $\cJ$ given by $(\cJ y)_n=a_ny_{n+1}+b_ny_n+a_{n-1}^*y_{n-1}$, $y_n\in \C^m$ (here ), where and are the…
