Query: Braneworld solutions for F(R) models with non-constant curvature   This work deal with braneworld scenarios with generalized gravity. We
investigate models where the potential of the scalar field is polynomial or
nonpolynomial. We obtain exact and approximated solutions for the scalar field,
warp factor and energy density, in the complex scenario with no restriction on
the scalar curvature. In particular, we describe the case where the brane may
split, engendering internal structure, with the splitting caused by the same
parameter that controls deviation from standard gravity.
