ABSTRACT: Density Functionals Theory is a theory developed by physicists to reduce the cost of the computation of the ground state energy of atomic, molecular and solid state systems. DFT consists in formulating in terms of the single particle density the variational problems which are usually formulated in terms of wave-functions. The mathematical understanding of the theory is very challenging from a variational point of view. I will try to give a concise introduction.
