A Nica-amenable submonoid of a group which fails to embed in an amenable group
Adam Dor-on, Boyu Li
We construct a weakly quasilattice-ordered submonoid of a group whose full semigroup -algebra is nuclear, while the monoid does not embed into any amenable group. Hen…
Obstructions to the full Hao-Ng isomorphism
Adam Dor-On, Ian Thompson
We show that the Hao-Ng isomorphism for full crossed products fails to hold. More precisely, for a non-degenerate -correspondence over a -algebra and a…
Products and factorization in operator systems
Adam Dor-On, Travis B. Russell
We study unital operator spaces endowed with a partially defined product. We give a matrix-norm characterization of such products that allows for a representation theorem where the…
On almost commuting unitary matrices
Adam Dor-On, Lucas Hall, Ilya Kachkovskiy
A question going back to Halmos asks when two approximately commuting matrices of a certain kind are close to exactly commuting matrices of the same kind. It has long been known th…
The Hao-Ng isomorphism theorem for reduced crossed products
Adam Dor-On, Ian Thompson
We prove the Hao-Ng isomorphism for reduced crossed products by locally compact Hausdorff groups. More precisely, for a non-degenerate -correspondence and a gener…
Shift equivalence relations through the lens of C*-correspondences
Boris Bilich, Adam Dor-On, Efren Ruiz
We continue the study of shift equivalence relations from the perspective of C*-bimodule theory. We study emerging shift equivalence relations following work of the second-named au…
