Abstract:
Alternative proofs of fundamental theorems about Cuntz-Krieger algebras for the C*-algebras of row-finite graphs are presented in this peer-reviwed mathematical paper; the latter are defined as directed graphs in which each vertex emits at most finitely many edges. Special cases of such theorems have been previously proven by employing andvanced software for high power digital computations.
