# Linear Stability of $f(R,\phi,X)$ Thick Branes: Tensor Perturbations

14 Nov 2018 Cui Zheng-Quan Liu Yu-Xiao Gu Bao-Min Zhao Li

We explore thick branes in $f(R,\phi,X)$ gravity. We obtain the linear tensor perturbation equation of $f(R,\phi,X)$ branes and show that the branes are stable against the tensor perturbations under the condition of $\frac{\partial f(R,\phi,X)}{\partial R}>0$... (read more)
