 Title: Generic AF-algebras

 Abstract  

 I will show that there are separable AF-algebras which map onto any separable AF-algebra. This universality is one of the consequences of a result showing that the category of finite-dimensional C*-algebras and left invertible homomorphisms is a Fraisse category. With the help of Fraisse theory we can describe the Bratteli diagram of the universal (Generic) AF-algebras, which belong to a class of separable AF-algebras which resemble C(2^N) in many senses. For instance, they have no minimal projections and tensorially absorb C(2^N).
