Description

In this talk, I will revisit the inflationary quantum cosmology framework where the Ashtekar formulation of gravity minimally coupled to a scalar field admits a full non-perturbative quantum minisuperspace description of inflation. By extending prior analytic treatments, I will show how inflation can be a robust dynamical attractor across a wide range of scalar potentials, even with mild slow-roll violations. This indicates that, in this formulation, inflation naturally emerges from generic initial conditions, and the quantum evolution can consistently extend beyond the classical singularity, opening the possibility of cyclic or pre-Big Bang phases and suggesting potential resolutions of the Borde-Guth-Vilenkin theorem.
