In this paper we study thick-shell braneworld models in the presence of a Gauss-Bonnet term. We discuss the peculiarities of the attainment of the thin-shell limit in this case and compare them with the same situation in Einstein gravity. We describe the two simplest families of thick-brane models (parametrized by the shell thickness) one can think of. In the thin-shell limit, one family is characterized by the constancy of its internal density profile (a simple structure for the matter sector… 
Braneworld dynamics in Einstein-Gauss-Bonnet gravity
We discuss the cosmological evolution of a braneworld in five-dimensional Gauss-Bonnet gravity. Our discussion allows the fifth (bulk) dimension to be spacelike as well as timelike. The resulting
Gauss-Bonnet Braneworld Redux: A Novel Scenario for the Bouncing Universe
We propose a new scenario for the bouncing universe in a simple five-dimensional braneworld model in the framework of Einstein-Gauss-Bonnet gravity, which works even with ordinary matter on the
Phantom-like effects in an asymmetric brane embedding with induced gravity and the Gauss–Bonnet term in the bulk
We construct an asymmetric braneworld embedding with induced gravity on the brane, where stringy effects are taken into account by the incorporation of the Gauss–Bonnet (GB) term into the bulk
Covariant gravitational equations on a brane world with a Gauss-Bonnet term
We present covariant gravitational equations to describe a four-dimensional brane world in the case with a Gauss-Bonnet term in a bulk spacetime, assuming that gravity is confined on the ${Z}_{2}$
A brane–bulk matter relation for a purely conical codimension-2 brane world
We study gravity on an infinitely thin codimension-2 brane world, with purely conical singularities and in the presence of an induced gravity term on the brane. We show that in this approximation,
Brane cosmology with curvature corrections
We study the cosmology of the Randall-Sundrum brane-world where the Einstein-Hilbert action is modified by curvature correction terms: a four-dimensional scalar curvature from induced gravity on the
Intersecting hypersurfaces and Lovelock Gravity
A theory of gravity in higher dimensions is considered. The usual Einstein-Hilbert action is supplemented with Lovelock terms, of higher order in the curvature tensor. These terms are important for
Tensor perturbations of f(R)-branes
Abstract We analyze the tensor perturbations of flat thick domain wall branes in f ( R ) gravity. Our results indicate that under the transverse and traceless gauge, the metric perturbations decouple
Gravitational resonances on f(R)-brane
In this paper, we investigate various f(R)-brane models and compare their gravitational resonance structures with the corresponding general relativity (GR)-branes. Starting from some known GR-brane
Brane-World Gravity
This review analyzes the geometry, dynamics and perturbations of simple brane-world models for cosmology and astrophysics, mainly focusing on warped 5-dimensional brane -worlds based on the Randall-Sundrum models.


Brane versus shell cosmologies in Einstein and Einstein-Gauss-Bonnet theories
We first illustrate on a simple example how, in existing brane cosmological models, the connection of a 'bulk' region to its mirror image creates matter on the 'brane'. Next, we present a
General Gauss-Bonnet brane cosmology
We consider five-dimensional spacetimes of constant three-dimensional spatial curvature in the presence of a bulk cosmological constant. We find the general solution of such a configuration in the
Braneworld Cosmology in (Anti)--de Sitter Einstein--Gauss--Bonnet--Maxwell Gravity
Braneworld cosmology for a domain wall embedded in the charged (Anti)-de Sitter-Schwarzschildblack hole of the five--dimensional Einstein-Gauss-Bonnet-Maxwell theory is considered. The effective
No ghost state of Gauss–Bonnet interaction in warped backgrounds
Abstract A general solution to the Einstein field equations with the Gauss–Bonnet (GB) term in an AdS 5 bulk background implies that the GB coupling α can take either sign (+ or −), though a positive
Thick branes and Gauss-Bonnet self-interactions
Thick branes obtained from a bulk action containing Gauss-Bonnet self-interactions are analyzed in light of the localization properties of the various modes of the geometry. The entangled system
Warped brane-world compactification, black hole thermodynamics and holographic cosmology with $R^2$ terms
We present a linear treatment of the Einstein-Gauss-Bonnet gravity on a singular co-dimension one brane embedded in (d + 1) dimension anti-de Sitter spacetimes. We exhibit that the zero-energy
Exact solutions and the cosmological constant problem in dilatonic domain wall higher curvature string gravity
In this paper, we extend the previous work by the authors, and elaborate further on the structure of the general solution to the graviton and dilaton equations of motion in brane world scenaria, in
Avoidance of Naked Singularities in Dilatonic Brane World Scenarios with a Gauss-Bonnet Term
Abstract We consider, in 5 dimensions, the low energy effective action induced by heterotic string theory including the leading stringy correction of order α′. In the presence of a single positive
Consistency of higher derivative gravity in the brane background
We consider the theory of higher derivative gravity with non-factorizable Randall-Sundrum type space-time and obtain the metric solutions which characterize the p-brane world-volume as a curved or
Exact braneworld cosmology induced from bulk black holes
We use a new, exact approach in calculating the energy density measured by an observer living on a brane embedded in a charged black-hole spacetime. We find that the bulk Weyl tensor gives rise to
