| contents | Based on the Rényi entropy, Rényi holographic dark energy has been proposed to explain the current accelerated expansion of the universe. In this paper, we analyze holographic inflation and slow-roll inflation within the framework of RHDE. Our results show that holographic inflation is ruled out by ACT DR6, while the slow-roll inflation with the power-law potential $V_{0}ϕ^{n}$ is favored by ACT DR6 for the cases $n=0.2$ and $0.3$, with $N$ in the range of $50$ to $55$. These findings suggest that RHDE provides a viable framework for slow-roll inflation while disfavoring the holographic inflation scenario. |
