On Warm Natural Inflation and Planck 2018 Constraints
<p dir="ltr">We investigate natural inflation with non-minimal coupling to gravity, characterized either by a quadratic or a periodic term, within the warm inflation paradigm during the slow-roll stage, in both strong and weak dissipation limits; and show that, in the case of a T-lin...
