Analytic Solution and Noether Symmetries for the Hyperbolic Inflationary Model in the Jordan Frame
The Noether symmetry analysis is applied for the study of a multifield cosmological model in a spatially flat FLRW background geometry. The gravitational Action Integral consists of two scalar fields, the Brans–Dicke field and a second scalar field minimally coupled to gravity. However, the two scal...
