Query: N-ification of Forces: A Holographic Perspective on D-brane Model
  Building   We study geometric aspects of extensions of the supersymmetric standard model
that exhibit a periodic duality cascade. Via the holographic correspondence,
the growth of the gauge group rank towards the UV is interpreted as a gradual
decompactification transition. We show that this class of models typically
develop a duality wall in the UV, and present an efficient method for
estimating the hierarchy between the on-set of the cascade and the formation of
the wall. As an illustrative example, we study the model introduced by
Cascales, Saad and Uranga in [14], which has an known geometric realization in
terms of D-branes on an SPP/Z_3 singularity.
