Dynamical aspects of asymmetric Eddington gravity with scalar fields

نویسندگان

چکیده

In Eddington gravity, the action principle involves only symmetric parts of connection and Ricci tensor, with a metric that emerges proportionally to latter. Here, we relax this character, prolong antisymmetric term, allow for various couplings scalar fields. We propose two possible invariant actions formed by distinct combinations independent tensors show generated must involve an additional part due relaxation symmetrization property. The comprehensive study shows second curvature influences dynamics connection, hence its solution in terms metric, evolution These new dynamical features are expected stand viable have interesting implications domains where fields indispensable.

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

The dynamical viability of scalar-tensor gravity theories

We establish the dynamical attractor behavior in scalar-tensor theories of dark energy, providing a powerful framework to analyze classes of theories, predicting common evolutionary characteristics that can be compared against cosmological constraints. In the Jordan frame the theories are viewed as a coupling between a scalar field, Φ, and the Ricci scalar, R, F (Φ)R. The Jordan frame evolution...

Three Dimensional Gravity in the Presence of Scalar Fields

We study a scalar field in curved space in three dimensions. We compare the results obtained by using perturbation theory and numerical solutions, especially regarding to singularity behaviour at infinity. We find that both methods point to the necessity of excising the space-time around the origin. key words: black holes, Choptuik formation, + [email protected] * [email protected]
