On the regularity of the density of electronic wavefunctions

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/97581We prove that the electronic density of atomic and molecular eigenfunctions is smooth away from the nuclei. The result is proved without decay assumptions on the eigenfunctions.New results after the talk by the first author at QMath-8, Taxco, Mexico, December 10-14, 2001.
