Abstract
We present an extension of the density-functional theory to the lowest states compatible with arbitrary constraints. A broad class of interesting excitation problems connected with charge and magnetization fluctuations can be treated by such a method. We demonstrate the usefulness in ab initio calculations for Ce impurities.
