Swampland dS conjecture in Mimetic $f(R, T)$ gravity
Abstract
In this paper, we study a theory of gravity called mimetic in the presence of swampland dS conjecture. For this purpose, we introduce several inflation solutions of the Hubble parameter H(N) from gravity model, in which R is Ricci scalar, and T denotes the trace of the energy-momentum tensor. Also, and are the free parameter and a number of e-fold, respectively. Then we calculate quantities such as potential, Lagrange multiplier, slow-roll, and some cosmological parameters such as and . Then we challenge the mentioned inflationary model from the swampland dS conjecture. We discuss the stability of the model and investigate the compatibility or incompatibility of this inflationary scenario with the latest Planck observable data.
