Berezin-Toeplitz Quantizationtroduced in a series of papers by F. A. Berezin . Subsequently, C. A. Berger and I undertook a detailed analytic study of Berezin’s operators in order to find an analog of the classical symbol calculus of pseudo-differential operators. In a series of papers , we dissected

Normal Elements of a Simple C*-Algebrae following elementary invariants: the spectrum of the element, the measure on its spectrum arising from each trace (or quasitrace) on the algebra, the K.-class of the spectral projection associated to each compact component of the spectrum together with the information whether the sum of these proj

The Generalized Weyl-von Neumann Theorem and C*-algebra Extensionsare unital and the surjective map from . to . is also unital. Furthermore, we assume that extensions are essential, i.e. . may be viewed as an essential ideal of .. The .-theory classifies those extensions when . = . and . = .(.), where . is the .*-algebra of compact operators on an infinite dimensi

On the Commutant Lifting Theorem and Hankel OperatorsIn this note we give another proof of the commutant lifting theorem (see) and ), based on the Adamjan-Arov-Krein techniques introduced in . We then apply the construction given in Theorem 1 below to obtain a generalization of a result in (see also ).

Elementary operators and subalgebrasIn this note, we construct an elementary operator on .(.) of length two which leaves invariant a nontrivial triangular subalgebra of .(.) but which cannot be written as a finite sum of elementary operators of length one that each leave the triangular subalgebra invariant.
