The Weyl group of the Cuntz algebra [PDF]

open access: yes, 2011
The Weyl group of the Cuntz algebra On is investigated. This is (isomorphic to) the group of polynomial automorphisms λu of On, namely those induced by unitaries u that can be written as finite sums of words in the canonical generating isometries S i and

On classification, UHF-stability, and tracial approximation of simple nuclear C*-algebras

open access: yes, 2014
In dieser Dissertation wird für eine C*-Algebra A aus bestimmten Klassen der einfachen separablen unitalen nuklearen C*-Algebren das Tensorprodukt von A und der universellen UHF-Algebra (Q) untersucht und bewiesen, dass es spurapproximativ eine ...

Classification of homomorphisms into simple Z-stable C⁎-algebras

open access: yes, 2011
We classify unital monomorphisms into certain simple Z-stable C⁎-algebras up to approximate unitary equivalence. The domain algebra C is allowed to be any unital separable commutative C⁎-algebra, or any unital simple separable nuclear Z-stable C⁎-algebra

The unitary group as an invariant of a simple unital C*-algebra

open access: yes, 2003
In 1954, H. Dye proved that the unitary groups of von Neumann factors not of type I2n determine the algebraic type of factors. Using Dye's result, M. Broise showed that any isomorphism between the unitary groups of two von Neumann factors not of type In

Endomorphisms of On which preserve the canonical UHF-subalgebra

open access: yes, 2009
Unital endomorphisms of the Cuntz algebra On which preserve the canonical UHF-subalgebra Fn are investigated. We give examples of such endomorphisms λ=λu for which the associated unitary element u in On (which satisfies λ(Sj)=uSj for all j) does not ...

Homomorphisms From C(X) Into C*-Algebras

open access: yes, 1997
Let A be a simple C*-algebra with real rank zero, stable rank one and weakly unperforated K0(A) of countable rank. We show that a monomorphism Φ: C(S2) → A can be approximated pointwise by homomorphisms from C(S2) into A with finite dimensional range if ...
