Abstract 



The electron density n(r,t), which is the central tool of timedependent density functional theory, is presently considered to be derivable from a onebody timedependent potential V(r,t), via oneelectron wave functions satisfying a timedependent Schrödinger equation. This is here related via a generalized equation of motion to a Dirac density matrix now involving t. Linear response theory is then surveyed, with a special emphasis on the question of causality with respect to the density dependence of the potential. Extraction of V(r,t) for solvable models is also proposed.
