Explicit Green operators for quantum mechanical Hamiltonians.~II.~ Edge type singularities of the helium atom
Heinz-Juergen Flad, Gohar Flad-Harutyunyan, Bert-Wolfgang Schulze
We extend our approach of asymptotic parametrix construction for Hamiltonian operators from conical to edge-type singularities which is applicable to coalescence points of two part…
Elliptic complexes on manifolds with boundary
B. -W. Schulze, J. Seiler
We show that elliptic complexes of (pseudo)differential operators on smooth compact manifolds with boundary can always be complemented to a Fredholm problem by boundary conditions…
The singular functions of branching edge asymptotics
B. -W. Schulze, L. Tepoyan
We investigate the structure of branching asymptotics appearing in solutions to elliptic edge problems. The exponents in powers of the half-axis variable, logarithmic terms, and co…
The Mellin-Edge Quantisation for Corner Operators
Bert-Wolfgang Schulze, Yawei Wei
We establish a quantisation of corner-degenerate symbols, here called Mellin-edge quantisation, on a manifold with second order singularities. The typical ingredients come from…
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…
Branching Asymptotics on Manifolds with Edge
B. -Wolfgang Schulze, Andrea Volpato
We study pseudo-differential operators on a wedge with continuous and variable discrete branching asymptotics.
