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
TLDR
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
