Corrections to inflationary models induced by non-minimal coupling between scalar field and curvature
I. V. Fomin, S. V. Chervon, E. S. Dentsel +1
In this paper, we consider possible corrections to the characteristics of inflationary models based on a specific parametrization of the non-minimal coupling between the scalar fie…
Einstein--Gauss--Bonnet Inflationary Cosmology in Phase- Formalism
Gevorg D. Manucharyan, Igor V. Fomin, Shivam Kumar Mishra +1
A central challenge in testing inflationary scenarios with cosmic microwave background (CMB) data is to derive predictions for cosmological observables that remain accurate beyond…
Inflationary models with a quadratic relationship between the parameters of cosmological perturbations
Igor V. Fomin, Vladimir L. Glushkov, Evgenii S. Dentsel +2
An approach to construct cosmological inflation models on the basis of a certain dependence of the scalar field evolution on the e-folds number is considered. The reconstruction of…
Effects of Matter Lagrangian in f(Q,T) Gravity: The Accelerating Cosmological Model
Rahul Bhagat, I. V. Fomin, B. Mishra
We investigate the logarithmic form of gravity with two different choices of matter Lagrangian such as: and . The parameters of the…
