Abstract
Recent progress in time-dependent Hartree-Fock (TDHF) theory is reviewed, with emphasis on new techniques and further generalizations. The formalism proposed by Moccia (ref.18) is sufficient to admit optimization of parameters of all kinds in a variational wavefunction determined by use of the Frenkel principle, the form of the reference function being arbitrary. Various approximations and methods of solution are discussed and an illustrative application, to the helium atom, is reported.
