Titre Pure C*-algebras of stable rank one
Horaire14:00 à 15:00
RésumeThe Cuntz semigroup has become increasingly important in connection with Elliott’s classification program. Our work further contributes to the evidence that a C*-algebraic dimension type property, so-called stable rank one, is deeply connected to purely algebraic properties of the Cuntz semigroup: almost divisibility and almost unperforation. In particular, we can show that in some cases stable rank one can be recovered from almost divisibility and almost unperforation.
