Modern Cosmologies from Empty Kaluza-klein Solutions in 5d
نویسنده
چکیده
We show that the empty five-dimensional solutions of Davidson-Sonnenschtein-Vozmediano, Phys. Rev. D32 (1985)1330, in the " old " Kaluza-Klein gravity, under appropriate interpretation can generate an ample variety of cosmological models in 4D, which include the higher-dimensional modifications to general relativity predicted by " modern " versions of noncompactified 5D gravity as, e.g., induced-matter and braneworld theories. This is the first time that these solutions are investigated in a systematic way as embeddings for cosmological models in 4D. They provide a different formulation, which is complementary to the approaches used in current versions of 5D relativity.

Self-similar cosmologies in 5D: spatially flat anisotropic models
In the context of theories of Kaluza-Klein type, with a large extra dimension, we study self-similar cosmological models in 5D that are homogeneous, anisotropic and spatially flat. The “ladder” to go between the physics in 5D and 4D is provided by Campbell-Maagard’s embedding theorems. We show that the 5-dimensional field equations RAB = 0 determine the form of the similarity variable. There ar...
متن کاملStrings from Flux Tube Solutions in Kaluza-Klein Theory
We calculate dimensional reduction of gravitational flux tube solutions in the scheme of Kaluza-Klein theory. The fifth dimension is compacified to a region of Planck size. Assuming the width of the tube to be also Planck size we obtain string-like object with physical fields originated from an initial 5D metric. The dynamics of these fields is inner one.
متن کاملFlux Tube Solutions in Kaluza-Klein Theory
Spherically symmetric, vacuum solutions in 5D and 7D Kaluza-Klein theory are obtained. These solutions are flux tubes with constant cross-sectional size, located between (+) and (-) Kaluza-Klein “electrical” and “magnetic” charges disposed respectively at r = ±∞ and filled with constant Kaluza-Klein “electrical” and “magnetic” fields. These objects are surprisingly similar to the flux tubes whi...
متن کاملWormholes and Flux Tubes in 5D Kaluza-Klein Theory
In this paper spherically symmetric, nonasymptotically flat solutions to 5D Kaluza-Klein theory, with “electric” and/or “magnetic” fields are investigated. It is shown that the global structure of the spacetime depends on the relation between the “electrical” and “magnetic” Kaluza-Klein fields. For small “magnetic” field we find a wormhole-like solution located between two null surfaces. As the...
متن کاملThe Behavior of Kasner Cosmologies with Induced Matter
We extend the induced matter model, previously applied to a variety of isotropic cases, to a generalization of Bianchi type-I anisotropic cosmologies. The induced matter model is a 5D Kaluza-Klein approach in which assumptions of compactness are relaxed for the fifth coordinate, leading to extra geometric terms. One interpretation of these extra terms is to identify them as an “induced matter” ...
