Abstract (summary)
We study the triangular subalgebras of UHF algebras which pro- vide new examples of algebras with the Dirichlet property and the Ando prop- erty. This in turn allows us to describe the semicrossed product by an isometric automorphism. We also study the isometric automorphism group of these al- gebras and prove that it decomposes into the semidirect product of an abelian group by a torsion free group. Various other structure results are proven as well.
