abstract

We investigate warm intermediate scenario of the cosmological inflation in $F(T)$ gravity in the limit of high dissipation. The inflationary expansion is driven by the scalar inflaton while the gravitational dynamics follow from the $F(T)$ gravity. We calculate the relevant inflationary observables such as scalar-tensor ratio, power-spectrum indices of density perturbations and gravitational waves and the e-folding parameter. We obtain a ratio of slow-roll parameters to be constant. Our calculations support the warm-intermediate inflationary scenario in a spacetime with torsion. Moreover our results are compatible with the astrophysical observations of cosmic microwave background and Planck data.

    gr-qc 2025-07 reject novelty 3.0 of 10

    The paper claims a torsion-based F(R,T) model can replace dark matter but provides no derivations, likelihoods, or data, leaving the claim unsupported.

    gr-qc 2025-07 reject novelty 3.0 of 10

    A survey-style comparative paper that asserts tunable F(R,T) gravity can match inflationary observables, without showing the promised numerical results.
