From Subfactors to Categories and Topology II. The quantum double of tensor categories and subfactors [PDF]

open access: yesJ. Pure Appl. Alg. 180, 159-219 (2003), 2001
We are concerned with the center (=quantum double) of tensor categories and prove generalizations of several results proven previously for quantum doubles of Hopf algebras. We consider F-linear tensor categories C with simple unit and finitely many isomorphism classes of simple objects. We assume that C is either a *-category (i.e. there is a positive *

The Range of Approximate Unitary Equivalence Classes of Homomorphisms from AH-algebras [PDF]

open access: yesarXiv, 2008
Let $C$ be a unital AH-algebra and $A$ be a unital simple C*-algebra with tracial rank zero. It has been shown that two unital monomorphisms $\phi, \psi: C\to A$ are approximately unitarily equivalent if and only if $$ [\phi]=[\psi] {\rm in} KL(C,A) and \tau\circ \phi=\tau\circ \psi \tforal \tau\in T(A), $$ where $T(A)$ is the tracial state space of $A.

Realizing Semigroup C*-Algebras As Groupoid C*-Algebras [PDF]

open access: yesarXiv, 2019
We show that semigroup C*-algebras are groupoid C*-algebras.

Successful treatment of post-intubation tracheal stenosis with balloon dilation, argon plasma coagulation, electrocautery and application of mitomycin C

open access: yesSouthwest Respiratory and Critical Care Chronicles, 2015
Tracheal stenosis is an uncommon but known complication of endotracheal intubation and tracheostomy. Surgery is currently the definitive treatment for tracheal stenosis but carries a significantly higher risk for adverse events as it often involves ...

On the C*-envelope of approximately finite-dimensional operator algebras [PDF]

open access: yesarXiv, 1995
The C*-envelope of the limit algebra (or limit space) of a contractive regular system of digraph algebras (or digraph spaces) is shown to be an approximately finite C*-algebra and the direct system for the C*-envelope is determined explicitly.

On the Realization of quantum gates coming from the Tracy-Singh product [PDF]

open access: yesarXiv
The Tracy-Singh product of matrices permits to construct a new gate $c \boxtimes c'$ from two $2$-qudit gates $c$ and $c'$. If $c$ and $c'$ are both Yang-Baxter gates, then $c \boxtimes c'$ is also a Yang-Baxter gate, and if at least one of them is entangling, then $c \boxtimes c'$ is also entangling.
