Abstract With the method of the background field expansion, we investigate the one-loop quantization of the Euclidean nonlocal f (R) model in the de-Sitter universe. We obtain the ghost-free condition (GFC) based on the transformation from the Jordan frame to the Einstein frame and the classical stability condition (CSC) satisfied $${f}_{RR}^{\left(0\right)}-{\phi }_{0}{F}_{RR}^{\left(0\right)} |
