## Abstract The time‐dependent variational principle due to Frenkel is derived from Hamilton's principle using a suitable general expression for the variational wave function. The connections with a recent comment of P. O. LΓΆwdin and P. K. Mukherjee on the same subject are discussed.

We investigate the Dirac time-dependent variational method for a system of non-ideal Bosons interacting through an arbitrary two body potential. The method produces a set of non-linear time dependent equations for the variational parameters. In particular we have considered small oscillations about

It is demonstrated that the least action time-dependent variational principle suggested by Kerman and Koonin is equivalent to Frenkel's variational principle. A set of equations suitable for the variational treatment of a number of time-dependent problems has been derived in the course of this analy
