Periodicity in Rank 2 Graph Algebras


Kumjian and Pask introduced an aperiodicity condition for higher rank graphs. We present a detailed analysis of when this occurs in certain rank 2 graphs. When the algebra is aperiodic, we give another proof of the simplicity of C(Fθ ). The periodic C*algebras are characterized, and it is shown that C(Fθ ) ' C(T)⊗A where A is a simple C*-algebra.
