Real analyticity away from the nucleus of pseudorelativistic Hartree-Fock orbitals

Anna Dall'Acqua, Søren Fournais, Thomas Østergaard Sørensen +1

We prove that the Hartree--Fock orbitals of pseudorelativistic atoms, that is, atoms where the kinetic energy of the electrons is given by the pseudorelativistic operator sqrt{-Del…
