Linear stability of f(R, ϕ, X) thick branes: tensor perturbations

Abstract We explore thick branes in 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}>...
