2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/105240We introduce a new multilevel domain decomposition method (MDD) for electronic structure calculations within semi-empirical and Density Functional Theory (DFT) frameworks. This method iterates between local fine solvers and global coarse solvers, in the spirit of domain decomposition methods.36 pages, 23 figures, submitted to Journal of Computational PhysicsComputational PhysicsChemical Physicstext
