Kaluza-Klein Higher Derivative Induced Gravity
نویسنده
چکیده
Kaluza-Klein higher derivative induced gravity is studied for its application in the inflationary universe. The stability of an inflationary solution in aD+4-dimensional anisotropic space is analyzed carefully. We show that there is two nontrivial constraints derived from the static assumptions on the D-dimensional scale factor d and scalar field ψ. We find that a physical inflationary solution is consistent with the above constraints. In addition, a compact formula for the non-redundant 4 + D dimensional Friedmann equation is also derived for convenience. Possible implications are also discussed in this paper.

Causal Anomalies in Kaluza-Klein Gravity Theories
Causal anomalies in two Kaluza-Klein gravity theories are examined, particularly as to whether these theories permit solutions in which the causality principle is violated. It is found that similarly to general relativity the field equations of the space-time-mass Kaluza-Klein (STM-KK) gravity theory do not exclude violation of causality of Gödel type, whereas the induced matter Kaluza-Klein (I...
متن کاملWarped Phenomenology of Higher - Derivative Gravity ∗ †
We examine the phenomenological implications at colliders for the existence of higher-derivative gravity terms as extensions to the Randall-Sundrum model. Such terms are expected to arise on rather general grounds, e.g., from string theory. In 5-d, if we demand that the theory be unitary and ghost free, these new contributions to the bulk action are uniquely of the Gauss-Bonnet form. We demonst...
متن کاملModern Cosmologies from Empty Kaluza-klein Solutions in 5d
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., induce...
متن کاملKaluza-klein Gravity in the Context of Modern Embedding Theories of the Spacetime
We review and discuss the original Kaluza-Klein theory in the framework of modern embedding theories of the spacetime, such as the recent induced matter approach. We show that in spite of their seeming similarity they constitute rather distinct proposals as far as their geometrical structure is concerned.
متن کاملNoncommutative Kaluza-Klein Theory
Efforts have been made recently to reformulate traditional Kaluza-Klein theory by using a generalized definition of a higher-dimensional extended space-time. Both electromagnetism and gravity have been studied in this context. We review some of the models which have been proposed, with a special effort to keep the mathematical formalism to a very minimum.
