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. Bazeia and J. D. Dantas, Phys. Rev. D, 85 (2012) 067303] to cases with multi scalar fields and with non-vanished spatial curvature, by using a different superpotential method.

To solve these equations, we introduce the following first-order formalism[This is a multi-field generalization of the first-order formalism in Ref. [ref] , where the authors first established the same first-order formalism for cosmological models with a single scalar.]: [equation] where $α>0$ is a positive parameter, $W$ and $Z$ are functions of ${ϕ^I}$, and are called as the superpotentials.
