de Sitter geometric inflation from dynamical singularities

Year: 2024

Type: article

Abstract: Within the framework of geometric inflation, where the Friedmann equation is modified to incorporate an infinite series of higher curvature corrections, we describe the emergence of a de Sitter inflationary phase near the poles of an arbitrary dynamical function. Our analysis is quite general and does not depend on any specific choice of cosmological dynamics. Published by the American Physical Society 2024
