Semiprojectivity for certain purely infinite C*-algebras
arXiv:math/0102229
Abstract
It is proved that classifiable simple separable nuclear purely infinite C*-algebras having finitely generated K-theory and torsion-free K_1 are semiprojective. This is accomplished by exhibiting these algebras as C*-algebras of infinite directed graphs.
