The action of the Thompson group F on infinite trees

Jeong Hee Hong, Wojciech Szymanski

We construct an action of the Thompson group F on a compact space built from pairs of infinite, binary rooted trees. The action arises as an F-equivariant compactification of the a…

On Conjugacy of Subalgebras in Graph -Algebras. II

Tomohiro Hayashi, Jeong Hee Hong, Wojciech Szymański

We apply a method inspired by Popa's intertwining-by-bimodules technique to investigate inner conjugacy of MASAs in graph -algebras. First we give a new proof of non-inner con…

On Conjugacy of Subalgebras of Graph C*-Algebras

Tomohiro Hayashi, Jeong Hee Hong, Sophie Emma Zegers +1

The problem of inner vs outer conjugacy of subalgebras of certain graph C*-algebras is investigated. For a large class of finite graphs E, we show that whenever is a vertex-fix…

Endomorphisms of the Cuntz Algebras and the Thompson Groups

Selçuk Barlak, Jeong Hee Hong, Wojciech Szymanski

We investigate the relationship between endomorphisms of the Cuntz algebra and endomorphisms of the Thompson groups , and represented inside the unitary…

On Conjugacy of MASAs in Graph -Algebras

Tomohiro Hayashi, Jeong Hee Hong, Wojciech Szymanski

For a large class of finite graphs , we show that whenever is a vertex-fixing quasi-free automorphism of the corresponding graph -algebra such that $α({\mathca…

On Endomorphisms of the Cuntz Algebra which Preserve the Canonical UHF-Subalgebra, II

Tomohiro Hayashi, Jeong Hee Hong, Wojciech Szymanski

It was shown recently by Conti, Rørdam and Szymański that there exist endomorphisms of the Cuntz algebra such that …
