Einstein-Gauss-Bonnet Gravity with Extra Dimensions
Galaxies, 2019 We consider a theory of modified gravity possessing d extra spatial dimensions with a maximally symmetric metric and a scale factor, whose ( 4 + d ) -dimensional gravitational action contains terms proportional to quadratic curvature scalars ...

Vacuum Energy in Saez-Ballester Theory and Stabilization of Extra Dimensions
Universe, 2022 In this work, we study a spherically symmetric metric in 5D within the framework of Saez-Ballester Theory, where minimal dark energy-matter interaction occurs. We predict that the expanding isotropic universe will be progressively DE dominated.

Thick brane in Rastall gravity
Journal of High Energy Physics, 2022 In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either

FLAVOR SYMMETRIES IN EXTRA DIMENSIONS [PDF]
Modern Physics Letters A, 2005 We present a class of models of flavor that rely on the use of flavor symmetries and the Froggart–Nielsen mechanism in extra dimensions. The particle content is that of the standard model plus an additional flavon field; all the fields propagate in universal extra dimensions and the flavor scale is associated with the cutoff of the theory, which in 5D

Local Regions with Expanding Extra Dimensions
Physics, 2021 In this paper possible spatial domains, containing expanding extra dimensions, are studied. It is demonstrated that these domains are predicted in the framework of f(R) gravity (where R is the scalar curviture) and could appear due to quantum ...

Extra dimensions and nonlinear equations [PDF]
Journal of Mathematical Physics, 2003 Solutions of nonlinear multi-component Euler–Monge partial differential equations are constructed in n spatial dimensions by dimension-doubling, a method that completely linearizes the problem. Nonlocal structures are an essential feature of the method.
