Cosmological twinlike models with multi scalar fields

Understand

We consider cosmological models driven by several canonical or noncanonical scalar fields.

• We show how the superpotential method enables one to construct twinlike models for a particular canonical model from some noncanonical ones.
• We conclude that it is possible to construct twinlike models for multi-field cosmological models, even when the spatial curvature is nonzero.
• This work extends the discussions of [D.
