A classification theorem for direct limits of extensions of circle algebras by purely infinite C*-algebras

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/76032We give a classification theorem for a class of C*-algebras which are direct limits of extensions of circle algebras by purely infinite C*-algebras. The invariant consists of the following: (1) the set of Murray-von Neumann equivalence classes of projections; (2) the set of homotopy classes of hyponormal partial isometries; (3) a map d; and (4) total K-theory.31 pagesOperator Algebras46L35A classification theorem for direct limits of extensions of circle algebras by purely infinite C*-algebrastext
