| Abstract: |

| The notion of nuclear dimension, introduced by Winter and Zacharias,
has provided a new, and very possibly the definitive, point of view for the
classification of separable simple nuclear C∗-algebras. In this thesis, the
C∗-algebras under consideration are crossed products of the type C oα N
where C is an approximately finite dimensional algebra and α is a corner endomorphism with the Rokhlin property. We compute their nuclear
dimension and show that they absorb the Jiang-Su algebra tensorially.
In light of the new guiding principle that nuclear dimension should imply classifiability, we then revisit previous work, largely due to Rørdam,
establishing the classifiability of such crossed products. |
