Perturbative Approximations to Avoid Matrix Diagonalization,used to initialize the density matrix iteration at the next step. Electron correlation methods based on the Hartree-Fock density matrix, without making reference to molecular orbitals are commented on.

Density Matrix Methods in Linear Scaling Electronic Structure Theory,ncreases exponentially with the number of iterations and the computational cost scales only linearly with the system size for sufficiently large sparse matrix representations. The methods are illustrated using simple models that are suitable for small numerical experiments.

Approximations of Long-Range Interactions in Fragment-Based Quantum Chemical Approaches,s, and proposed solutions are discussed. Finally, with the fragment-based adjustable density matrix assembler (ADMA) method as example, the capacities but also some limitations of the presented approaches will be presented using different test systems.
