Does cold inflation with dissipation mechanism in nonequilibrium thermodynamic prescription imply warm inflation?

Abstract

The present work is an attempt to find inter relationship between the cold and warm inflationary scenarios. Here cold inflation is described by a single scalar field (inflaton) and nonequilibrium thermodynamical prescription is imposed. It is found that this quasi-de-Sitter phase of evolution is equivalent to warm inflation. The present work also addresses the question whether the dissipation is Hawking-type or not.
