The Weyl group of the Cuntz algebra
Roberto Conti, Jeong Hee Hong, Wojciech Szymanski
The Weyl group of the Cuntz algebra O_n, with n finite, is investigated. This is (isomorphic to) the group of polynomial automorphisms of O_n, namely those induced by unitaries tha…
Automorphisms of the Cuntz algebras
Roberto Conti, Wojciech Szymanski
We survey recent results on endomorphisms and especially on automorphisms of the Cuntz algebras O_n, with a special emphasis on the structure of the Weyl group. We discuss endomorp…
The Cuntz Algebra Q_N and C*-Algebras of Product Systems
Jeong Hee Hong, Nadia S. Larsen, Wojciech Szymanski
We consider a product system over the multiplicative semigroup N^x of Hilbert bimodules which is implicit in work of S. Yamashita and of the second named author. We prove directly,…
Endomorphisms of the Cuntz Algebras
Roberto Conti, Jeong Hee Hong, Wojciech Szymanski
This mainly expository article is devoted to recent advances in the study of dynamical aspects of the Cuntz algebras O_n, with n finite, via their automorphisms and, more generally…
Endomorphisms of graph algebras
Roberto Conti, Jeong Hee Hong, Wojciech Szymanski
We initiate a systematic investigation of endomorphisms of graph C*-algebras C*(E), extending several known results on endomorphisms of the Cuntz algebras O_n. Most but not all of…
