Quintessential α-attractor inflation:
a dynamical systems analysis
Artur Alho,
Claes Uggla
Abstract:The equations for quintessential α-attractor inflation
with a single scalar field, radiation and matter in a spatially flat
FLRW spacetime are recast into a regular dynamical system on a
compact state space. This enables a complete description of the
solution space of these models. The inflationary attractor solution
is shown to correspond to the unstable center manifold of a de
Sitter fixed point, and we describe connections between slow-roll
and dynamical systems approximations for this solution, including
