More localized automorphisms of the Cuntz algebras

Roberto Conti, Jason Kimberley, Wojciech Szymanski

We completely determine the localized automorphisms of the Cuntz algebras $O_{n}$ corresponding to permutation matrices in $M_{n} \otimes M_{n}$ for $n = 3$ and $n = 4$ . This result is obtai…

Computing the Jones index of quadratic permutation endomorphisms of O_2

Roberto Conti, Wojciech Szymanski

We compute the index of the inclusions of type $I I I_{1/2}$ factors arising from endomorphisms of the Cuntz algebra $O_{2}$ associated to the rank-two permutation matrices.

Labeled Trees and Localized Automorphisms of the Cuntz Algebras

Roberto Conti, Wojciech Szymanski

We initiate a detailed and systematic study of automorphisms of the Cuntz algebras $Ø_{n}$ which preserve both the diagonal and the core $U H F$ -subalgebra. A general criterion of inve…
