Query: Strong Deflection Limit Lensing Effects in the Minimal Geometric
  Deformation and Casadio-Fabbri-Mazzacurati Solutions   In this paper we apply the strong deflection limit approach to investigate
the gravitational lensing phenomena beyond general relativity. This is
accomplished by considering the lensing effects related to black hole solutions
that emerge out of the domain of Einstein gravity, namely, the ones acquired
from the method of geometric deformation and the Casadio-Fabbri-Mazzacurati
brane-world black holes. The lensing observables, for those brane-world black
hole metrics, are compared with the standard ones for the Schwarzschild case.
We prove that brane-world black holes could have significantly different
observational signatures, compared to the Schwarzschild black hole, with terms
containing the post-Newtonian parameter, for the case of the
Casadio-Fabbri-Mazzacurati, and terms with variable brane-world tension, for
the method of geometric deformation.
