Analytic Solution and Noether Symmetries for the Hyperbolic Inflationary Model in the Jordan Frame
نویسندگان
چکیده
The Noether symmetry analysis is applied for the study of a multifield cosmological model in spatially flat FLRW background geometry. gravitational Action Integral consists two scalar fields, Brans-Dicke field and second minimally coupled to gravity. However, fields interact kinetic terms. This has been found describe equivalent hyperbolic inflation Jordan frame. application Noether's theorems constrain free parameters that conservation laws exist. We find equations form an integrable dynamical system analytic solution derived.
