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…
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 …
Pure infiniteness and ideal structure of -algebras associated to Fell bundles
B. K. Kwaśniewski, W. Szymański
We investigate structural properties of the reduced cross-sectional algebra of a Fell bundle over a discrete group . Conditions allowing one t…
On Cohomology for Product Systems
Jeong Hee Hong, Mi Jung Son, Wojciech Szymanski
A cohomology for product systems of Hilbert bimodules is defined via the Ext functor. For the class of product systems corresponding to irreversible algebraic dynamics, relevant re…
