"WebThis will certainly be smaller than the full unknown functional of the kinetic operator. And second, the difference between the exact electron-electron interaction and it's equivalent in the Hartree approximation. Again, given that this is already a more than decent approximation, this energy difference will be smaller than the full exact value. " - Hartree operator
