On the Essential Spectrum of N-Body Systems with Asymptotically Homogeneous of Order Zero Interactions
Vladimir Georgescu, Victor Nistor
We overview some of our recent results on the essential spectrum of N-body Hamiltonians with potentials defined by functions that have radial limits at infinity. The results extend…

Boundary value problems and layer potentials on manifolds with cylindrical ends
Marius Mitrea, Victor Nistor
We extend the method of layer potentials to manifolds with boundary and cylindrical ends. To obtain this extension along the classical lines, we have to deal with several technical…

Pseudodifferential operators on manifolds with a Lie structure at infinity
Bernd Ammann, Robert Lauter, Victor Nistor
Several examples of non-compact manifolds whose geometry at infinity is described by Lie algebras of vector fields (on a compactification of to a mani…
