# Logic Seminar - Daoud Siniora - "Automorphism groups of homogeneous structures"

A special class among the countably infinite relational structures is the class of homogeneous structures. These are the structures where every finite partial isomorphism extends to a total automorphism. A countable set, the ordered rationals, and the random graph are all homogeneous.
