Query: Complexity factor of spherically anisotropic polytropes from
  gravitational decoupling   In this work we will analyse the complexity factor, proposed by L. Herrera,
of spherically symmetric static matter distributions satisfying a polytropic
equation through the gravitational decoupling method. Specifically, we will use
the 2-steps GD, which is a particular case of the Extended Geometric
Deformation (EGD), to obtain analytic polytropic solutions of Einstein's
equations. In order to give an example, we construct a model satisfying a
polytropic equation of state using Tolman IV as seed solution.
