Title: 
Forcing axioms and the rigidity of corona algebras III

Abstract:  In the final talk of this series, I will recap some of the discussion from last time and prove one of the results mentioned; namely I will prove that, assuming Todorcevic's Axiom, every map determined by a coherent family of *homomorphisms must have a Borel graph.
