On the quantum origin of inflation in the geometric inflation model

Understand

In this paper we investigate the cosmological dynamics of geometric inflation by means of the tools of the dynamical systems theory.

• We focus in the study of two explicit models where it is possible to sum the infinite series of higher curvature corrections that arises in the formalism.
• These would be very interesting possibilities since, if regard gravity as a quantum effective theory, a key feature is that higher powers of the curvature invariants are involved at higher loops.
• Hence, naively, consideration of the whole infinite tower of curvature invariants amounts to consideration of all of the higher order loops.
