The specific setup investigated leads to branes with a time-dependent warp factor. We calculate the effective Hubble parameter and the effective scale factor for the FLRW branes obtained solutions. The spatially dependent branes solutions also were found.

We show that a scenario of thick branes in five dimensions with compact extra dimension in the framework of the f (R)-Einstein-Palatini theory is possible by the accomplishment of an assertive criteria. We finalize investigating the outputs of the resulting sum rules with respect to a stabilization mechanism.

dimensional case with compact extra dimension. In studing the speci c consistency conditions in the Brans-Dicke gravity we were able to show that the brane generating scalar field
potential is relevant for relaxing the gravitational constraints.
