*f*(

*R, ϕ, X*) gravity. We obtain the linear tensor perturbation equation of

*f*(

*R, ϕ, X*) branes and show that the branes are stable against the tensor perturbations under the condition of ∂ f R ϕ X ∂ R > 0 $$ \frac{\partial f\left(R,\phi, X\right)}{\partial R}>0 $$ . In order to obtain thick brane solutions of the fourth-order field equations in...

*R*,

*T*) theories of gravity, with

*R*the Ricci scalar and

*T*the trace of the energy-momentum tensor. We try to get the analytic background solutions and discuss the full linear perturbations, especially the scalar perturbations. We compare how the brane world model is modified with that of general relativity coupled to a canonical...

*f*(

*R*) gravity. Working in the Einstein frame, we show that these solutions are stable against small linear perturbations, including the tensor, vector, and scalar modes. For both models, the corresponding gravitational zero mode is localized on the brane, which leads to the four-dimensional Newton law; while the...

*f*(

*R*)-brane models and compare their gravitational resonance structures with the corresponding general relativity (GR)-branes. Starting from some known GR-brane solutions, we derive thick

*f*(

*R*)-brane solutions such that the metric, scalar field, and scalar potential coincide with those of the corresponding GR-branes.We find that for the branes generated by a single...

*f*(

*R*) gravity with $$f(R)=R \,+\, \alpha R^2$$ f ( R ) = R + α R 2 in Bazeia et al. (Phys Lett B 729:127 2014). In these solutions, the inner brane structure can be turned on by tuning the value of the parameter $$\alpha $$ α . In this paper, we investigate how the parameter $$\alpha $$ α affects...
