Systematic approximations to the optimized effective potential: Application to orbital-density-functional theory

The integral equation originally derived by Sharp and Horton for the optimized effective potential (OEP) is exactly transformed into an equivalent form from which it is manifestly clear that the OEP, ${\mathit{V}}_{\mathit{x}\mathrm{\ensuremath{\sigma}}}^{0}$(r), is an implicit functional of only {$...
