Ricci cosmology
  We revisit spatially flat FLRW cosmology in light of recent advances in
standard model relativistic fluid dynamics. Modern fluid dynamics requires the
presence of curvature-matter terms in the energy-momentum tensor for
consistency. These terms are linear in the Ricci scalar and tensor, such that
the corresponding cosmological model is referred to as ``Ricci cosmology''. No
cosmological constant is included, there are no inflaton fields, bulk viscosity
is assumed to be zero and we only employ standard Einstein gravity. Analytic
solutions to Ricci cosmology are discussed, and we find that it is possible to
support an early-time inflationary universe using only well-known ingredients
from the Standard Model of physics and geometric properties of space-time.
