Minimal Finite Models

##
Jonathan Ariel Barmak and Elias Gabriel Minian

We characterize the smallest finite spaces with the same homotopy groups as
the spheres. Similarly, we describe the minimal finite models of any finite
graph.We also develop new combinatorial techniques based on finite spaces to
study classical invariants of general topological spaces.
