    "abstract": "The time-dependent density-matrix theory (TDDM) gives a correlated ground\nstate as a stationary solution of the time-dependent equations for one-body and\ntwo-body density matrices. The small amplitude limit of TDDM (STDDM) is a\nversion of extended RPA theories which include the effects of ground state\ncorrelations. It is shown that the solutions of the Hartree-Fock Bogoliubov\ntheory and the quasi-particle RPA satisfy the TDDM and STDDM equations,\nrespectively, when only pairing-type correlations are taken into account in\nTDDM and STDDM.",
