Abstract
The standard Friedmann-Lemaitre-Robertson-Walker (FLRW) model is modif
ied to include particle production processes. The influence of these p
rocesses on the dynamics of the early Universe is investigated. We arg
ue that a sufficiently high creation rate may give rise to an inflatio
nary period. A stability analysis about this background yields growing
energy density perturbations during the de Sitter stage.
