Inflationary Solutions in the Simplest Gravity Model with Conformal Symmetry

نویسندگان

چکیده

We discuss a model of gravity with conformal symmetry appearing in the simplest extension General Relativity Poincar\'e algebra terms. The nonlinear realization causes existence five scalar fields. Therefore it looks desirable to use them for driving inflation at earliest stages Universe evolution. It is shown that evolution scale factor doesn't imply accelerated expansion so there are no inflationary solutions this model. To drive more complicated induced by Poincare required.

Asymptotic Symmetry Algebra of Conformal Gravity

We compute asymptotic symmetry algebras of conformal gravity. Due to more general boundary conditions allowed in conformal gravity in comparison to those in Einstein gravity, we can classify the corresponding algebras. The highest algebra for non-trivial boundary conditions is five dimensional and it leads to global geon solution with non-vanishing charges.

On stability of simplest nonsingular inflationary cosmological models within general relativity and gauge theories of gravity

In this paper we provide approximate analytical analysis of stability of nonsingular inflationary chaotic-type cosmological models. Initial conditions for nonsingular solutions at the bounce correspond to dominance of potential part of the energy density of the scalar field over its kinetic part both within general relativity and gauge theories of gravity. Moreover, scalar field at the bounce e...

On the inflationary solutions in higher - derivative gravity with dilaton field

We discuss the existence of de Sitter inflationary solutions for the string-inspired fourth-derivative gravity theories with dilaton field. We consider a space-time of arbitrary dimension D and an arbitrary parametrization of the target space metric. The specific features of the theory in dimension D = 4 and those of the special ghost-free parametrization of the metric are found. We also consid...

The Simplest Exact Solutions in the Ltb Model

The rules of calculating three undetermined functions which defined a solution in the LTB model are used to study the class of exact nonhomogeneous models with f (μ) = 1, Λ = 0. The parameter ν(μ) defined the difference between LTB and FRW models is found out and the limit transformation to the FRW model is shown. The initial conditions are present throught density and Habble function at the mo...

Conformal Symmetry and the Standard Model

We re-examine the question of radiative symmetry breaking in the standard model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of classically unbroken conformal symmetry, besides naturally introducing and stabilizing a hierarchy, is compatible with all available data; in particular, there exists...
