Classical and quantum exact solutions for a FRW multi-scalar field cosmology with an exponential potential driven inflation

J. Socorro, Omar E. Núñez, Rafael Hernández-Jiménez

A flat Fiedmann-Robertson-Walker (FRW) multi-scalar field cosmology is studied with a particular potential of the form $\mathrm{V}(\varphi ,\sigma )={\mathrm{V}}_0{\mathrm{e}}^{-{\lambda }_1\varphi -{\lambda }_2\sigma }$, which emerges as a relati…
