On the classification of simple amenable $C*$-algebras with finite decomposition rank, II
, 2023 We prove that every unital stably finite simple amenable $C^*$-algebra $A$ with finite nuclear dimension and with UCT such that every trace is quasi-diagonal has the property that $A\otimes Q$ has generalized tracial rank at most one, where $Q$ is the ...

Maximal UHF subalgebras of certain C*-algebras
A well-known result in dynamical systems asserts that any Cantor minimal system $(X,T)$ has a maximal rational equicontinuous factor $(Y,S)$ which is in fact an odometer, and realizes the rational subgroup of the $K_0$-group of $(X,T)$, that is, $\mathbb{

Strongly self-absorbing property for inclusions of c*-algebras with a finite Watatani index
, 2014 Let P ⊂ A be an inclusion of unital C*-algebras and E: A → P be a conditional expectation of index-finite type. We introduce a Rokhlin property for E and discuss the D-absorbing property, where D is a separable, unital, strongly self-absorbing C*-algebra,

Commutants of unitaries in UHF algebras and functorial properties of exactness.
Journal für die reine und angewandte Mathematik (Crelles Journal), 1994 It is shown that the maximal \(C^*\)-algebra tensor product \(N\otimes^{\max} A\) of a von Neumann algebra \(N\) and a unital separable \(C^*\)-algebra \(A\) with lifting property has a faithful *-representation \(d\) on a Hilbert space such that \(n\in N\mapsto d(n\otimes 1)\) is normal.
