چکیده
We discuss the cosmological inflation in context of $f(Q)$ non-metric gravity, where $Q$ is scalar. After introducing conformal transformations for we first focus on potential-slow-roll by studying corresponding potentials different forms function Einstein frame. Secondly, investigate Hubble-slow-roll three classes inflationary considered specific form $f(Q)\propto Q^{2}$, Jordan compare results both approaches with observations coming from Planck and BICEP2/Keck array satellites. Observational constraints parameters space models are obtained as well.

Slow roll in simple non-canonical inflation
We consider inflation using a class of non-canonical Lagrangians for which the modification to the kinetic term depends on the field, but not its derivatives. We generalize the standard Hubble slow roll expansion to the non-canonical case and derive expressions for observables in terms of the generalized slow roll parameters. We apply the general results to the illustrative case of “Slinky” inf...
متن کاملGeneralized slow-roll inflation
The slow-roll approximation to inflation is ultimately justified by the presence of inflationary attractors for the orbits of the solutions of the dynamical equations in phase space. There are many indications that the inflaton field couples nonminimally to the spacetime curvature: the existence of attractor points for inflation with nonminimal coupling is demonstrated, subject to a condition o...
متن کاملInflation without slow roll
We draw attention to the possibility that inflation (i.e. accelerated expansion) might continue after the end of slow roll, during a period of fast oscillations of the inflaton field φ. This phenomenon takes place when a mild non-convexity inequality is satisfied by the potential V (φ). The presence of such a period of φ-oscillation-driven inflation can substantially modify reheating scenarios....
متن کاملSlow Roll Inflation in Non-Minimally Coupled Theories: Hyperextended Gravity Approach
The slow roll approximation is studied for cosmological models in Hyperextended Scalar-Tensor Theories of Gravity. A procedure to obtain slow roll solutions in non-minimally coupled gravity is outlined and some examples are provided. An integral condition over the functional form of the non-minimal coupling is imposed in order to obtain intermediate inflationary behavior. e-mail: dtorres@venus....
متن کاملBrane inflation without slow-roll
The scenario of brane inflation without using the conventional slow-roll approximations has been investigated. Based on the mechanism of generating the curvature perturbations at the end of inflation, a new brane inflation paradigm was developed. The conditions for making a sufficiently large enough number of e-foldings and for generating the curvature perturbations without producing dangerous ...
