摘要: We characterise stable finiteness of the C*-algebra a cofinal k-graph in terms an algebraic condition involving coordinate matrices graph. This result covers all simple C*-algebras. In special case 2-graphs we further prove that AF-embeddability, quasidiagonality and 2-graph algebra are equivalent.
