Inflation after curvature bounce
Abstract
Abstract We present a stable cosmological model of a closed universe in the presence of conventional scalar field. The stability of the model and the 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 spectral index $$n_s$$ n s and the tensor-to-scalar ratio, while the number of e-folds is treated as a model parameter. We present several sets of parameters that satisfy the current observational data.
