Conformal analogs of the Jordan-Brans-Dicke theory. II. (models including vacuum effects)

  • Published:
Astrophysics Aims and scope

This paper is part of a series based on a modified Jordan tensor-scalar theory of gravitation. Given the current importance of research on vacuum phenomena in cosmic evolution, we examine several standard cosmological models with a scalar field and a physical vacuum, including models that have a dominant scalar field with the vacuum energy taken into account in various conformal representations of the Jordan theory, as well as models in which ordinary matter that obeys the conventional equations of state is present. Some noteworthy results are obtained which are, to a certain extent, consistent with currently available observational data.
