Regular Bouncing Solutions, Energy Conditions and the Brans-Dicke Theory
  In general, to avoid a singularity in cosmological models involves the
introduction of exotic kind of matter fields, for example, a scalar field with
negative energy density. In order to have a bouncing solution in classical
General Relativity, violation of the energy conditions is required. In this
work, we discuss a case of the bouncing solution in the Brans-Dicke theory with
radiative fluid that obeys the energy conditions, and with no ghosts.
