{\(s^*\)}-compressibility of the discrete Hartree-Fock equation (English)
0 references
The paper studies the \(s^{*}\)-compressibility for Galerkin discretizations of the Hartree-Fock equation in wavelet bases. The authors focus on compression of the Galerkin matrices from nuclear Coulomb potentials and nonlinear terms in the Fock operator which hitherto has not been discussed in the literature. Numerical results are also discussed.
