Particle Creation with Generalised Gravitational and Cosmological Constants


N. Ibotombi Singh and Y. Bembem Devi


In this paper we study the effect of particle creation on the evolution of
FRW cosmological model. The universe has been considered as an open thermodynamic system when particle creation leads to supplementary negative creation pressure in addition to the thermodynamic pressure. We also discuss dynamical behaviors of the cosmological solutions of radiation dominated models and stiff models.

Keywords and Phrases : Particle creation, open thermodynamic system,
negative pressure.
