Inflationary attractors from a non-canonical kinetic term

Published 18 Jun 2021 in gr-qc | (2106.10303v1)

Abstract: We show explicitly how the T-model, E-model, and Hilltop inflations are obtained from the inflation models with a non-canonical kinetic term and an arbitrary potential. By this method, any attractor of observables $n_s$ and $r$ is possible. The presence of attractors poses a challenge to differentiate inflation models.
