Probing the possibility of inflation realization with viscous cosmology

The research presented in the current article explores the potential for inflation realization in a cosmic environment with bulk viscosity using a tachyon scalar field. The present study rewrites the entropy conservation equation to take bulk viscosity into account. The work's initial phase examined the behaviour of the equation of state parameter for logamediate, intermediate, and emergent scenarios within a framework of viscous cosmology having the viscosity coefficient in linear and polynomial forms. The study then focused on the relative dominance of the scalar field and potential for the tachyon scalar field in the presence of bulk viscosity for the different choices of scale factor and came to the conclusion that the prerequisite for the realization of inflation is met in the framework of bulk viscosity.
