abstract

The curvature singularity in viable f(R) gravity models is examined when the background density is dense. This singularity could be eliminated by adding the $R^{2}$ term in the Lagrangian. Some of cosmological consequences, in particular the source for the scalar mode of gravitational waves, are discussed.

Discussion (0). Continue with ORCID to comment.

  1. Preventing Curvature Singularities in $f(R)$ Dark Energy Models

    gr-qc 2025-08 reject novelty 4.0 of 10

    Adding R² or related higher-curvature corrections can prevent singularities in toy f(R) dark-energy models only when the correction mass is tuned far below the Starobinsky inflation scale.
