General solutions to $$\mathcal {N}$$ N -field cosmology with exponential potentials
Abstract We construct the general analytical solution for the $$\mathcal {N}$$ N -field product-exponential potential in an expanding FLRW background. We demonstrate the relevance of this analytical solution in more general contexts for the derivation of estimates for the transitional time between a...
