Cosmological solutions in spatially curved universes with adiabatic particle production

Understand

We perform a qualitative and thermodynamic study of two models when one takes into account adiabatic particle production.

• In the first one, there is a constant particle production rate, which leads to solutions depicting the current cosmic acceleration but without inflation.
• The other one has solutions that unify the early and late time acceleration.
• These solutions converge asymptotically to the thermal equilibrium.
