WebDensity Functional Theory. Firstly we need to reduce as far as possible the number of degrees of freedom of the system. Our most basic approximation does just this. It is called the Born-Oppenheimer approximation . A functional is a function of a function. In DFT the functional is the electron density which is a function of space and time.
