Abstract

We present a stable cosmological model of a closed universe in the presence of conventional scalar field. The stability of the model and absence of singularity is ensured by spatial curvature without the need for additional peculiar matter. We reconstruct the Lagrangian and numerically compute observational predictions, including the number of e-folds, the spectral index nsn_s, and the tensor-to-scalar ratio. We present several sets of parameters that satisfy the current observational data.
