Ellipticity of quantum mechanical Hamiltonians in the edge algebra
Heinz-Juergen Flad, Gohar Harutyunyan
We have studied the ellipticity of quantum mechanical Hamiltonians, in particular of the helium atom, in order to prove existence of a parametrix and corresponding Green operator.…

Explicit Green operators for quantum mechanical Hamiltonians. I. The hydrogen atom
Heinz-Jürgen Flad, Gohar Harutyunyan, Reinhold Schneider +1
We study a new approach to determine the asymptotic behaviour of quantum many-particle systems near coalescence points of particles which interact via singular Coulomb potentials.…
