Ellipticity of the quantum mechanical Hamiltonians: corner singularity of the helium atom

In paper (Flad and Harutyunyan in Discrete Contin Dyn Syst 420–429, 2011 ) is shown that the Hamiltonian of the helium atom in the Born–Oppenheimer approximation, in the case if two particles coincide, is an edge-degenerate operator, which is elliptic in the corresponding edge calculus. The aim of t...
