摘要
In this work we investigate the entropic information measure in the context of braneworlds with nonconstant curvature. The braneworld entropic information is studied for gravity modified by the square of the Ricci scalar, besides the usual Einstein-Hilbert term. We showed that the minimum value of the brane configurational entropy provides a stricter bound on the parameter that is responsible for the F(R) model differing from the Einstein-Hilbert standard one. Our results are moreover consistent to a negative bulk cosmological constant.
