Rellich's theorem and N-body Schrodinger operators
K. Ito, E. Skibsted
We show an optimal version of the Rellich theorem for generalized many-body Schrodinger operators. It applies to singular potentials, in particular to a model for atoms and molecul…
Sommerfeld radiation condition at threshold
Erik Skibsted
We prove Besov space bounds of the resolvent at low energies in any dimension for a class of potentials that are negative and obey a virial condition with these conditions imposed…
Global solutions to the eikonal equation
J. Cruz-Sampedro, E. Skibsted
We study structural stability of smoothness of the maximal solution to the geometric eikonal equation on (Rd, G), d \geq 2. This is within the framework of order zero metrics G. Fo…
Regularity of Bound States
J. Faupin, J. S. Møller, E. Skibsted
We study regularity of bound states pertaining to embedded eigenvalues of a self-adjoint operator , with respect to an auxiliary operator that is conjugate to in the sen…
