چکیده
Abstract We investigate the regularized four-dimensional Einstein–Gauss–Bonnet (4 D EGB) gravity with a non-minimal scalar coupling function, which is an extension of 4 EGB theory. By introducing to Gauss-Bonnet term, we demonstrate additional contribution dynamical equations otherwise absent in dimensionally Furthermore, analyze stability system by using approach based on fixed points. Then, consider time evolution history universe and constrain observational data obtain cosmological parameters model.

Synchronization analysis of complex dynamical networks with hybrid coupling with application to Chua’s circuit
Complex dynamic networks have been considered by researchers for their applications in modeling and analyzing many engineering issues. These networks are composed of interconnected nodes and exhibit complex behaviors that are resulted from interactions between these nodes. Synchronization, which is the concept of coordinated behavior between nodes, is the most interested behavior in these netwo...
متن کاملRemarks on the quantum gravity interpretation of 4D dynamical triangulation
Here the path integral is over real metrics modulo coordinate transformations, G denotes a renormalized Newton constant and the · · · indicate higher derivative terms like R, etc. There may also be nonlocal terms related to the conformal anomaly [2]. The integral over μ produces the volume fixing delta function δ( ∫ dx √ g − V ). If this integral were done in the saddle point approximation, the...
متن کاملMetric-scalar gravity with torsion and the measurability of the non-minimal coupling
The “measurability” of the non-minimal coupling is discussed by considering the correction to the Newtonian static potential in the semi-classical approach. The coefficient of the “gravitational Darwin term” (GDT) gets redefined by the non-minimal torsion scalar couplings. Based on a similar analysis of the GDT in the effective field theory approach to non-minimal scalar we conclude that for re...
متن کاملInflation by non-minimal coupling
Inflationary scenarios based on simple non-minimal coupling aφ2R and its generalizations are studied. First, generalizing the form of non-minimal coupling to K(φ)R with an arbitrary function K, we show that the flat potential still is obtainable when V (φ)/K2(φ) is asymptotically constant. Very interestingly, if the ratio of the dimensionless quartic coupling(λ) of the inflaton field and the no...
متن کاملQuantum Cosmology in Scalar-tensor Theories with Non Minimal Coupling
Quantization in the minisuperspace of non minimal scalar-tensor theories leads to a partial differential equation which is non separable. Through a conformal transformation we can recast the Wheeler-DeWitt equation in an integrable form, which corresponds to the minimal coupling case, whose general solution is known. Performing the inverse conformal transformation in the solution so found, we c...
