Abstract
The problem of v-representability had cast a shadow of uncertainty over density functional theory (DFT). Building on CCR, the topology of the v(r)-n(r) mapping is clarified. The Be series and a lattice model are used for rl, to a continuous variable, r, does not appear to offer difficulties.
