The Gaussian time-dependent variational equations are used to explored the physics of (, 4 ) 3+1 field theory. We have investigated the static solutions and discussed the conditions of renormalization. Using these results and stability analysis we show that there are two viable non-trivial versions

We investigate the time-dependent variational equations in \(\phi^{4}\) field theory. We show that the standard method for renormalization applies to these time-dependent equations. The crucial point is to use the hamiltonian nature of the variational principle. In particular we have considered smal

## Abstract This paper proposes a direct, quantumโ€mechanical definition for ฮ“ (effective action) using a twoโ€step procedure for applying the variational principle to timeโ€dependent quantum problems.
