Extended Warm Inflation

Abstract

A bidimensional parameter space of unitary area is introduced to study phenomenologically the dynamic and thermodynamic behavior of inflationary models driven by a scalar field coupled to a thermal component. In this enlarged context the isentropic and warm pictures are just extreme cases of an infinite two-parametric family of possible inflationary scenarios. It is also shown that strong couplings are responsible by an alteration in the standard slow roll conditions which relax the smallness constraint on the first and the second derivatives of the potential.
