Title: On the model theory of the Farey graph and the free factor complex
(joint work with Z. Mohammadi)
Abstract: The free factor complex of a free group of finite rank shares many properties with finite dimensional projective spaces.
I will explain the geometry of the free factor complex and will show how to see that at least for rank 2 the complex is
\omega-stable.
