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.…

Asymptotic Parametrices of Elliptic Edge Operators
H. -J. Flad, G. Harutyunyan, B. -W. Schulze
We study operators on a singular manifold, here of conical or edge type, and develop a new general approach of representing asymptotics of solutions to elliptic equations close to…
