In this short review, we revisit inflation in F(R)-gravity. We find several F(R)-models for viable inflation by applying some reconstruction techniques. A special attention is payed in the reproduction of the last Planck satellite data. The possible generalizations of Starobinsky- like inflation are found and discussed. The early-time acceleration is analyzed in a higher- derivative quantum gravitational model which mainly reduces to F(R)-gravity.

Discussion (0). Continue with ORCID to comment.

  1. Inflation in non-local hybrid metric-Palatini gravity

    hep-th 2024-12 conditional novelty 6.0 of 10

    Non-local hybrid metric-Palatini gravity generically contains ghosts, but a degenerate subclass with metric f(R) gravity plus Palatini non-local terms is ghost-free and can drive slow-roll inflation resembling Starobi...

  2. Canonical Scalar Field Inflation with a Woods-Saxon Potential

    gr-qc 2019-08 reject novelty 3.0 of 10

    A Woods-Saxon (logistic) scalar potential is claimed to produce Planck-compatible inflation and reheating, but the supporting slow-roll equations contain sign and algebra errors.
