چکیده
We consider the existence of a Noether symmetry in the scalar-tensor theory of gravity in flat Friedman Robertson Walker (FRW) cosmology. The forms of coupling function ω(φ) and generic potential V (φ) are obtained by requiring the existence of a Noether symmetry for such theory. We derive exact cosmological solutions of the field equations from a point-like Lagrangian.

Scalar Field Cosmologies with Viscous Fluid
We investigate cosmological models with a free scalar field and a viscous fluid. We find exact solutions for a linear and nonlinear viscosity pressure. Both yield singular and bouncing solutions. In the first regime, a de Sitter stage is asymptotically stable, while in the second case we find power-law evolutions for vanishing cosmological constant. PACS 04.20 Jb, 04.40 Nr, 98.80 Hw
متن کاملNew exact solutions for inflationary cosmological perturbations
From a general ansatz for the effective potential of cosmological perturbations we find new, exact solutions in single-scalar-field inflation: A three parameter family of exact solutions that encompasses all exact solutions that have been known previously (power-law inflation, Easther’s model, and a generalized version of Starobinsky’s solution). The main feature of this new family is that the ...
متن کاملAn Exact Cosmological Solution of the Coupled Einstein-Majorana Fermion-Scalar Field Equations
We couple a neutral scalar field and a Majorana fermion field to Einstein gravity represented by the Robertson-Walker metric and find a class of exact cosmological solutions.
متن کاملScalar Field Cosmologies with Perfect Fluid in Robertson-walker Metric
Several isotropic, homogeneous cosmological models containing a self-interacting minimally coupled scalar eld, a perfect uid source and cosmological constant are solved. New exact, asymptotically stable solutions with an in ationary regime or a nal Friedmann stage are found for some simple, interesting potentials. It is shown that the uid and the curvature may determine how these models evolve ...
متن کاملSome Impacts of Lorentz Violation on Cosmology
The impact of Lorentz violation on the dynamics of a scalar field is investigated. In particular, we study the dynamics of a scalar field in the scalar-vector-tensor theory where the vector field is constrained to be unity and time like. By taking a generic form of the scalar field action, a generalized dynamical equation for the scalar-vector-tensor theory of gravity is obtained to describe th...
