Influence of higgs particles on cosmological models

It is shown that a conformally invariant scalar field can have anomalous vacuum expectation values in a Tolman universe of any kind: closed, quasi-Euclidean, or open. The anomalous vacuum expectation values lead in the initial stages of evolution of the universe to the existence of negative energy in the closed and quasi-Euclidean models if the square of the unrenormalized mass is negative and, in the open model, if the square of the unrenormalized mass is less than the square of the Planck mass. The influence of the negative energy on cosmological models of any type with and without Λ term is investigated. It is shown that there is no singular state.
